The Colorado Trail (CT) runs 500 miles from Denver to Durango. It travels through some of the most spectacular country in Colorado, through 6 wilderness areas and eight mountain ranges. The CT was first conceived in 1974, but was not completed until the late 1980's.

Summary of supported FKT progression for the full Colorado Trail:
1988 Dale Garland, Dave LaFranboise, John McAward, John Wolgamott about 17d (W-E, Collegiate East)
1999 Buzz Burrell 11d16h13m (E-W, Collegiate East)
2003 Betsy Kalmeyer 9d10h52m (E-W, Collegiate East)
2003 Hal Koerner 9d10h19m (E-W, Collegiate East)
2006 Jonathan Basham 8d13h28m (E-W, Collegiate East)
2008 Paul Pomeroy 8d12h14m5s (W-E, Collegiate East)   
2013 Scott Jamie 8d7h40m (W-E, Collegiate East)
2017 Bryan Williams 8d0h30m (W-E, Collegiate West)


Summary of unsupported FKT progression for the full Colorado Trail:

2004 Demetri "Coup" Coupounas about 20d
2006 Paul Pomeroy 14d9h30m 
2012 Shawn Forry 10d19h5m (E-W)
2016 John Zahorian 9d12h32m (E-W)


The first speed record on the Colorado Trail happened in 1988, almost immediately after the trail was completed -- so soon that the route was hard to follow in many spots. Dale Garland, Dave LaFranboise, John McAward and John Wolgamott ran from Durango to Denver in about 17 days.

Buzz Burrell & Peter Bakwin hit the CT back in 1999. They started the eastern end (Waterton Canyon) because it meant they could sleep at home in Boulder the night before the start, and because most backpackers go east to west. Bakwin got injured after 7 days and had to stop. Burrell went on to lower the record to 11d16h13m.

In 2003, Betsy Kalmeyer smashed Burrell's record, running 9d10h52m. Betsy's time was beaten just 3 days later and by only a few minutes by Hal Koerner, 9d10h19m (shows the advantage of knowing the existing record!) Both Kalmeyer and Koerner ran east to west.

Jonathan Basham ran 8d13h28m (east to west) in July 14-22, 2006, supported by AT-record-holder Andrew Thompson. Basham's daily splits are here.

The La Sportiva Adventure Running blog has some great information about Paul Pomeroy's CT record, which I'll quote extensively here:

"Paul Pomeroy of Lyons, Colorado just broke Jonathan Basham’s Colorado Trail Record. Paul went 'under the radar' by choice; almost no one knew he was even on the Trail. 'I did it entirely for personal reasons', he notes. 'I didn’t want to talk it up. I wanted to do it'. Paul is well-known in local running circles as an outstanding athlete, with a great wit and sense of honor. Fortunately he is also gracious and articulate, and generously shared a few words with me about his recent trip:

It was definitely arduous. That’s an understatement. It just about finished me off. Let me just say I’m not looking to repeat this anytime soon. Getting toward Denver the heat became a problem. My feet were swollen and my shin hurt, but decided to go for broke and pay the price after. I taped it up, took some Advil, and did 74 miles the last day. I left at 1 AM and reached Waterton (the northern terminous) at 12:15 AM the next night. That was on about 1 hour of sleep to begin with. I basically made a last desperate burst to Waterton, looking at my watch the whole way.

Paul clocked 8 days, 12 hrs, 14 mins, 5 seconds, bettering the previous mark by about one and a quarter hours. The record is tight! Paul shared more interesting thoughts:

I could only move so fast. So its how long can you keep moving? It’s like nothing else I’ve ever done. A sleep deprivation thing. Sometimes I couldn’t walk a straight line, sometimes my eyes couldn’t focus. 18-20 hours a day ... it’s hard to believe a person can keep it going ... not real high on the fun factor, that’s for sure. My crew was great; obviously it was a team effort. It was my wife Suzanne, my mother, and my son Ethan was along too. We only had a couple of missteps; cost maybe 2 hours total. We had a pop-up camper which was essential.

Towards the end of his CT run, in a very unusual twist, Paul met Sam Thompson running the other direction with the same intention:

I was surprised to meet Sam on the Trail, going the other way. There’s only a one month period when you can do these things, so I thought I’d do it now and maybe have the Record for one year. While I’m not exactly going to root for him to break my record, I’m not against him either ... he’s a nice guy, and I set out to do a certain thing, and I did it, so I’m happy. Someone will always be faster … I thought it was possible to do this in 8 days flat, and I couldn’t do that ... someone else probably can, if they can run more. When Jonathan did it he was 29; that’s a good age ... I’m 47, and I don’t know if I have another one of these left in me. I emailed him my time, so he would know. That’s only fair; I knew Basham’s time, and went for it, so he should know mine."

Sam Thompson's trip began July 25, 2008, at Waterton Canyon, and was recorded daily in a blog. The blog reports the decision to quit as follows:
It was a heartbreaking decision, but Sam and Kirsten very wisely decided to pull out with 70 miles to go. Essentially, logistics and the inaccessibility of the trail is what mattered in the end, not Sam's ability to keep going. Here's what happened: Earlier in day 8, Kirsten and one of the photographers tried to forge a creek, but the engine flooded, rendering the Jeep inoperable (it had to be towed away). Because the crew couldn't reach Sam's checkpoint, he kept going while drinking water from the creek / river and eating the food he had left. Meanwhile, Kirsten and the photographer hitchhiked into Silverton, met up with Kirsten's parents, and somehow made it to the next checkpoint. When Sam arrived at the checkpoint, a decision had to be made. The crew couldn't find a local marathoner on such short notice to accompany Sam on the nighttime leg of day 8 (there are actually quite a few ultramarathoners in Silverton), so the two options were:
a) For Sam to tackle the trail at night by himself
b) To call it.
Although nobody doubted that Sam could physically keep going until the end, safety had to be the biggest concern. Badly fatigued (yet still determined, persistent, and able), Sam would have taken a huge risk to keep going without some assurance that the crew could make it to the next checkpoint. Further, without a running partner to help Sam navigate, staying on the trail in complete darkness would have been just too much of a risk to take.

David Horton also made a failed attempt to break Paul Pomeroy's supported record for the Colorado Trail, starting on July 4, 2009, at Waterton Canyon. Horton was supported by former CT record holder, Jonathan Basham. As indicated on this website, Horton had metabolic problems and had to stop after completing 330 miles in 6 days. Here are some exerpts from Horton's report on the blog of his trip:

Going after the CT record might have been my most difficult multi-day attempt so far. The CT record is very TOUGH. The trail itself was tougher than I thought it would be. I averaged 40 miles per day on the PCT and AT and 45 miles per day running across America. Averaging over 54 miles per day on the CT was VERY tough. I started every day before daylight, usually around 4:00 AM and finished every day after dark. My average time on the trail was around 17 hours per day. This left very little time for anything. I was usually in bed 30 to 45 minutes after finishing each day. Each day, the last section ATE my lunch. It took everything that I had to finish each day. I never knew at night if I would be able to go again the next day... Could I have run the next day? Yes. Could I have caused myself or others some serious problems? Yes... I hope that God blesses all of you as he has blessed me. Seek your dreams and goals. -- David Horton

Scott Jamie did the CT fully supported in 11d12h46m, September 2-13, 2009. This is a fast time, but still 3 days over the record.

Matt Hart went after the CT record (supported) in July 2010, but only managed 9d7h48m. This is still the 3rd fastest time, and it speaks to the difficulty of the current record. Matt's blog is here.

After 3 days I had run 180.6 miles to the dam road by Twin Lakes. I was now 10 miles ahead of the record pace. But I paid for it the following day where I only logged 38 miles and couldn't stay awake. And so it goes, I made a lot of mistakes, didn't plan well enough for some sections, was stranded a few times and hypothermic once. None of that matters or tarnishes the experience because that is the experience. All of these things are expected when the goal is something this huge. -- Matt Hart

Scott Jamie returned to the CT and broke the supported record, running west to east in 8d7h40, August 16-24, 2013. More info and photos on

Jamie's supported FKT was broken by Bryan Williams, who ran the CT in 8d0h30m, August 26 - September 3, 2017. Williams went west to east and took the Collegiate West option, which appears to be a little (83 vs. 78 miles) longer than the standard Collegiate East route, with a more vertical and overall higher elevation. He started with Eric Truhe, who suffered a stress fracture after 3.5 days (200 miles) and had to stop. Williams' tracker data was archived by

While supported and unsupported records on the CT have been contested for years, only recently has a fast self-supported trip been reported. Brandon Stapanowich hiked the CT in 9d14h28m, July 6-15, 2016, using standard thru-hiker style, including 3 resupplies en route (as indicated below). Stapanowich hiked west to east, and took the somewhat harder Collegiate West option (longer, more vertical gain, higher elevation). More info is below.

The CT has also seen a few truly unsupported trips. Unsupported means you carry all your food from the start, basically getting nothing but water en route. The CT was first done this way in 2004 by Demetri (Coup) Coupounas, the founder of GoLite, in about 20 days. Coup carried a big pack full of food, but also lost 25 lbs body weight on the hike. Coup also did the JMT and the LT unsupported that year, completing the "Triple Gem" of backpacking. In another of his classic trips, Paul Pomeroy attacked the CT unsupported in 2006 -- with a vow of silence for the entire trip. Paul finished in 14d9h30m, dropping 16 lbs of body weight that he could ill-afford to lose. In August 2012, Shawn Forry crushed Pomeroy's unsupported time by hiking the trail (east to west) in a remarkable 10d19h5m. Forry carried a SPOT Tracker, and his track is archived on A very detailed report with daily splits is on Forry's blog. He reports doing a few things that could be considered (small) violations of unsupported and FKT efforts, including: taking food/calories from happenstance sources ("Trail Magic") on 4 occasions, totalling 3 sodas and some fruit slices; buying a repair kit for his sleeping pad; disposing of trash and un-needed food along the way; and walking off-route (but not fewer miles) on 4 occasions to obtain water. John Zahorian reports hiking the CT unsupported in a very fast 9d12h32m, July 11-20, 2016. While it took Zahorian 6 months to complete a trip report (his video, while long, is really worth watching!), we see no reason to dispute his claim of a new unsupported FKT. Bronson Hargreaves reports a remarkable unsupported time for the CT of 8d18h7m, August 14-23, 2016, less than 18 hours slower than the fully supported record! However, we look forward to seeing additional information and verification data Hargreaves' trip before acknowledging a new unsupported FKT (see discussion on our old website). Hargreaves made a second attempt in 2017, but stopped after 109 miles, a few hours behind FKT pace.

In an interesting innovation, a group of 5 men ran the CT relay style in 3d15h54m, Sept. 7-10, 2017, as reported by the Durango Herald. The runners were Brett Sublett, Kyle Curtin, Tate Lagasca, Holden Rennaker and Shaun Burke. Such relays have not been common for trail FKT attempts, but could add an interesting new element if standards can be created.

The CT also hosts an informal mountain bike race. Mountain bikers must deviate from the hiker route in several places to avoid wilderness areas. The guiding principles of the race are simply stated as follows: Solo, self-supported. This is a very pure style of racing with a strict code of ethics. The guiding principles are 'Do it yourself.' and 'Equal opportunity.' In 2007 Jefe Branham set the fastest time at 5d5h30m (followed just 20 minutes later by Stefan Griebel). In the 2008 race Ethan Passant lowered the mark to 5d2h26m. But, a week later Owen Murphy did the route as an "individual time trial" in a stunning time of 4d8h45m. Murphy's report includes the following lines that I think will resonnate with many who engage in these types of individual adventures:

I can only shake my head in disbelief at the good fortune I encountered along the Colorado Trail: perfect weather, interesting people, no major mechanicals, and no major physical or mental meltdowns. I cashed in some serious good karma along the way and I am very grateful to everybody who loaned me some of theirs (I’ll pay you back)! The stars may never align like that again, but I’m already hoping they do next summer.

Stefan Griebel combined biking and hiking, to cover the entire official CT in 7d20h from July 28 to August 5, 2006. His report is here.

I'd like to publicly announce that I will be attempting the overall unsupported fkt on the Colorado Trail from Denver to Durango starting this Saturday 7/14/2018.

This will follow a traditional unsupported fkt attempt- 

I will carry everything except water from start to finish. 

I will not accept any trail magic, support, or outside assistance.

I will not be picking up caches or supplies at any point.

I will be on foot the entire time and accept no muleing/pacing etc.

I will be using a SPOT device to track my location at various times along the way. I will send off a location at night and some point during each day. There will be no live tracking due to battery life. 

I will be posting updates on Instagram if you want to follow along (@colahikes).

I’m excited to follow behind those who have hiked before me especially those who have set/ attempted the fkt already. 


Good luck Cola! Hope you have a safe and successful journey!

The CT officially reopened today.

I'd like to publicly announce that I will be attempting the overall SELF-supported FKT on the Colorado Trail from Denver to Durango starting this Monday 7/16/2018. I will likely start at 0400. I will try to better the current self-supported FKT at 9d14 hrs and ideally JZ's FKT at 9d12 as it is lower than current self-supported.


This will follow a traditional self-supported "thru-hiker"  FKT attempt.

I will not accept any trail magic, support, or outside assistance.

I will use mail drops, caches and businesses as necessary. I will only have a total of 3 resupplies.

I will be on foot the entire time and accept no muling/pacing etc.

I will be using an Inreach device to track my location along the way. I will likely send off a location at night. There will be live tracking as long as battery management is reasonable. For verification, I will also use a Garmin Fenix 3 which has GPS as well to backup Inreach.

My inreach link is here:

I am excited to go for this. It will motivate me that Cola is on route too. I will most likely never see him (he'll be 100 miles ahead when I start!)  but it will be nice to have a "rabbit" way ahead of me!


JZ's time is amazing and I'm excited to try to beat it. Lets pray for rain and no more fires.


I am starting a female supported FKT attempt of the CO Trail tomorrow late afternoon in Durango. Here is the link to my DeLorme:

I will be going from Durango to Waterton Canyon and taking the east variation in the Collegiate area. I will have plenty of witnesses, photo documentation, and written documentation in addition to the DeLorme. I posted the link on Facebook, and my husband, other crew, and friends who run with me likely will update that post with information and pictures (or create separate posts) on a regular basis.

My connection to the CO Trail is strong, and I'm really looking forward to spending the next 9ish days out there!

Sheila stopped at Carson Saddle early this morning.  She was a attacked and injured by sheep dogs yesterday afternoon, and needed to have her injuries attended too.  Really a shame as she seemed to be doing very well!


Hi guys, I want to announce that I am attempting an unsupported FKT attempt of the CT from Durango to Denver this July. I am going to be carrying all of my food from start to finish. There will be no outside support. I will be taking the CW route. Wish me luck! 

Hello all, 

I am planning a FKT attempt for self-supported Colorado Trail East-West w CWE route. Thru-hiker style. No outside assistance including trail magic. Will begin in Waterton, July 21, 2019. Attempting to best John Zahorian’s and Brandon Staponowich’s records. It will be a huge challenge as their times are very strong.

Hopefully, there won’t be too much avalanche debris and downed trees! I will post my inreach link so I can be tracked. I will attempt to maintain tracking whenever moving, unless I have battery life issues. I will also verify a successful FKT attempt with my Garmin watch.

Third times the charm?


Just a bit of clarification, are you attempting a SELF supported FKT or an UN supported FKT?  John Zahorian holds the FKT for unsupported at 9d12h32m.  Brandon Stapanowich holds the FKT for the self supported at 9d14h28m.  Self supported means you would have mailed packages to resupply.  Unsupported means you will have everything with you from beginning to end with no resupply or outside support whatsoever.  

Are you SELF or UN supported?  Also, please send your garmin Inreach link.  

Hello FKT world!

I will be attempting an UNsupported FKT on the Colorado Trail beginning August 1st at 5 AM.  I will be traveling from Waterton Canyon to Durango and use the Collegiate East route.  I will carry all my food and supplies from start to finish and not accept any outside assistance, to include no trail magic.  I have informed John Zahorian, current unsupported FKT holder, of my attempt.  My attempt can be followed/verified by my Garmin Inreach device in two places:

Garmin Inreach:


I will also have the ability to post on Twitter (@mexifast) and FB along the way via the Garmin Inreach.  

I was unable to complete my journey on the Colorado Trail.  I was unprepared mentally and physically to go unsupported.  My FKT attempt ended pretty early as I was only able to complete ~35 miles a day for 3 days with a much too heavy pack.  I'm really intrigued to become more efficient in the mountains based on this attempt.  

Big congrats to Dr. Dre for setting the Self-Supported FKT!  


Good effort! I can’t imagine unsupported.

One of the main reasons I did the Colorado Trail was seeing your documentary in Durango back in the day. Great job on all your efforts. Maybe someday our paths will cross.


David is doing a great job. I hope he can continue. It’s nice to see so much activity on the record. Take care, dre’

I noticed that as of this morning David Ruttum declared a new UNsupported FKT for the Colorado Trail. However, his initial announcement said he was starting a "fully supported" attempt starting on August 4. While tracking his spot, it appears that all of his sleeps were at road crossings. Based on this as well as the language in the updates, someone else was with him likely helping him.

Given this, I wish to challenge this being the new UNsupported record. Here are David's announcements and updates [emphasis mine]:

I intend to challenge the current fully supported FKT on Colorado Trail Northbound with Colorado Trail West. I will start in Durango morning of Sunday 4 August.

Day 1 (8/04):  Left Junction Creek TH about 5:00AM.  David hiked until about 2AM and slept a bit at Little Molas Lake, about 72 miles.

Day 2 (8/05):  Reached Hwy 149, 127.2 miles (55 for the day).

Day 3 (8/06):  Hwy 114, 182.2 miles in 3 days!

Day 4 (8/07):  Marshall Pass, 217.8 miles.

Day 5 (8/08):  Cottonwood Pass (Collegiate West), 218 miles to go.

Day 6 (8/09):  Twin Lakes, 181.2 miles to go.

Day 7 (8/10):  Cataract Creek (east of Camp Hale), 134.3 miles to go.

Day 8 (8/11):  N Fork Swan River, 91.4 miles to go.

Day 9 (8/12):  At 10PM David took a break of less than 3 hours at Wellington Lake Rd, 40.4 miles to go.  He started again around 12:45AM, leaving him about 16h45m to break John Zahorian's unsupported FKT! GO!

Day 10 (8/13):  Finished at Waterton Canyon TH about 2:30PM, for a total time of about 9d9h30m !  NEW UNSUPPORTED FKT by about 3 hours!

My bad! Somehow I got it mixed up in my mind. Supported is right, so no FKT. I’ll fix that ASAP. (David made no such claim - entirely my fault.)

Hello everyone!

I am planning a Self Supported FKT attempt of the Colorado Trail, collegiate East, thru hiker style with no outside support including trail magic beginning Friday September 6th around 6am MST from Waterton Canyon. I’ll be attempting to break Andre Michaud’s record of 8 days 23 hours and 16 minutes which will be very difficult. I have a lot of respect for this record and this trail and I know it will be quite the test. I will be caching food, picking up mail drops, and buying food along the way. I am sharing my Garmin link so you can follow my progress along the way and verify a new record if one is set. 

Garmin inreach :


I had to abandon my Self Supported FKT effort today due to a quad injury unfortunately. 

Starting July 18th, 2020 I will be attempting to beat the current self-supported FKT on the Colorado Trail (East to West, Collegiate East) held by Andre Michaud. I will be tracking my trip with a SPOT device and a GPS watch which I will be uploading to Strava. I will be doing it "thru-hiker style" as Scott Williamson laid out in his 2008 FKT - no support crew, using mail drops, and picking up food and supplies in towns along the way. No rides in vehicles – unless injured or ill and needing medical attention.

I will be attempting to set a self-supported female FKT for the East to West, Collegiate West route of the Colorado Trail starting on July 24th, 2020. I will be using mail drops and purchase supplies along the way, without any pre-arranged outside support. I will be tracking my trip with an Inreach device from which I will send my location at some points throughout the day (battery life permitting) and at the end of the day. You can follow my progress at:

Hello all,

I will attempt to improve on Joe Grant's (le bon coureur franco-americain) SUPPORTED FKT of E-W Colorado Trail (8d20h09m), Collegiate west variant. In keeping with social distancing, I will have a one-man support team, my oldest friend, David Greedy. 

I'm planning to start early morning August 5th at Waterton CYN. 

I'm excited by another opportunity and humbled by the many attempts in the last few years.

My inreach will be transmitting my location from start to finish every day, assuming no issues with battery life, etc. I will likely have a backup Garmin if necessary. I will turn off at night. 

My garmin:


Cheers, Andre'

I'd like to publicly announce that I will be attempting a supported FKT on the Colorado Trail from Durango to Denver starting 07/27/2020. 

I will be using a Garmin Inreach

I will be taking the Collegiate East route.

Announcing it makes it feel pretty real.

Hey everyone!

I will be attempting the Unsupported FKT on the Colorado Trail from Denver to Durango on Thursday, August 6th.  I will be carrying all of my own gear and food from start to finish and will not have any pacers or outside support of any kind.  I will be taking the Collegiate East Route and attempting to beat the current record of 9 days, 12 hours, and 32 minutes set by Mr. John Zahorian.

I will be using my Garmin 935 as well as a Garmin Inreach Mini for backup (and live tracking) which I will turn off at night.

Hello Internet!

Today (7/30) I will begin an attempt to break Olga King's self-supported FKT for the CT. 

I have three mail drops. I have no pre-arranged support (mailing, pacing, etc). I will be on foot the entire time--if I get in a vehicle the attempt's a no-go.

I will be using an Inreach device to track my location (once a an hour if battery life permits. I will also send off a location each night (so my mom can sleep ?) and once during the day just to be extra sure. I'm happy to make that data public after the attempt (the FKT guys have it for now). I will be posting public updates on my insta: @mikaelaosler.



I just would like to state that Mikaela's record is absolutely stunning. Biggest take away is that it was SO close to male record, only a day difference! And the dedication it takes to do more than a handful of days of such mileage on this terrain. It'll stay here for a long time. Supported records are great, but this whole thing "nobody but myself" is a whole different universe. Way to go, girl! Full respect. Not many females want and able to go alone the whole way, and push to that extend. Also, congrats on VT.

Making the official announcement, in about 12 hours I'll be leaving Durango on my attempt to establish a Denver bound, Collegiate East self supported FKT and challenge Andre Michaud's current overall self supported FKT. Doing it fully self supported - no pacers, no crews, no friends meeting me to drop supplies or hike with me. I'm planning to not get in a car to follow Andre's footsteps, however if a planned resupply location falls through due to closure, missing package, or some other unforseen circumstance I may then hitch hike in order to resupply, returning to the exact location I left the trail.

I'll be tracking on my watch and uploading to Strava - . In addition I'll be taking lots of pictures and videos, including pictures showing my watch in front of recognizable landmarks for further verification.

Good Morning! 
I’m excited to announce that I’ll be attempting the Colorado trail female FKT. Going NOBO collegiate East, Supported and carrying all my own gear. Picking up resupplies from friends along the way. 
I will be posting and having a friend post to Facebook/Instagram during the trip. 
I can not wait to explore 500 sMiles of beautiful Colorado! 
Feeling real now that it’s on the page! 

The link to my SPOT device that I’ll be using to track. Also tracking with my COROS and uploading to Strava. 

Hi FKT world! 

On Wednesday 9/9 (or Thursday depending on Tuesday’s storm) I plan on attempting to break Mikaela bad ass self supported record on the Colorado Trail, Denver to Durango, Collegiate East. I have three boxes sent, no pre arranged support, and will be on foot the entire time.  
I have a Garmin to track location (made public when finished), will keep a log on my phone, pictures with time stamps to verify and post to Instagram @paigepasquini when service permits. 

Very exciting!

My name is Milissa Gillen (Mary Poppins) and I will be attemping to hike the Colorado Trail from Durango to Denver, West to East, Collegiate West beginning 9/13/2020. I will hike in traditional thru hiker style, self-supported, picking up resupply at three locations along the way where I have mailed packages. Since there is no official FKT for this route, in this style, and for Women, my time will be establishing the FKT should I succeed in completing the entire route. My goal is under 14 days because thats how much time I have! Undoubtedly someone will come along and do it faster than me in the near future, but this is an honor to give this a try! I will have a Garmin InReach for tracking, camera on my phone, and will post on IG/FB as Im able (milissajayn). Looking forward very much to this time in the great mountains of Colorado!

I will be attempting to hike the Colorado Trail from Durango to Denver, West to East (also known as NoBo), Collegiate West. I am starting around this weekend (4th of July). I will hike in traditional through-hiker style, UN-supported, following all the rules: carry all food and gear from the start, NO resupply at any point, no help accepted in any way, shape or form (including no trail angels or begging off strangers), no pacers, crew, etc, carry out my trash (unless it's safe to burn per LNT and fire bans rules), water only from natural sources. My goal is under 14 days. I will have a live link to Spot Gen-4 (provided for authorities to follow but kept private otherwise until I am done) for tracking, camera on my phone for photos, and a Garmin watch for mileage.I am excited to be back on a trail I love so much, this time "backwards". Here's to no crazy lightening on the ridges and a lack of kitties.

Olga King

Unfortunately, despite physically I was ready (much better than 2018), I live high, and train high, something weird happened, and I, literally, had a hard time to breathe even on easiest climbs. By day 3, during longer steeper sections, I had to stop sucking air every minute or so. Did 44.5, 39, 36.5 miles. Doing the math, I was getting closer to 14 than 12 days, and while I had the time and could stretch the food easily, I came to make some solid FKT, not simply "I was the only one, and a finish will warrant the name here" (like my first time, which was so easily broken exactly because I didn't exert my ability and smelled the roses, and even knitted in the tent, ha). It was my only attempt at something this huge. At 51, and after 8 years of OTS (that dreaded athlete fatigue), it was fun to dream. I tried to do it for the "older folks with no ultralight stuff", good ol' style. But, the body decided otherwise. I want to love and enjoy the mountains well into sunset, and taking that much time off with a family and a job is a one-time shot. I love this sport, but it's time to chill. Sad, but truth. Thanks to the FKT people for doing this stuff!

Hear, hear, Olga! I'm coming after some Unsupported action this year. Need to set a benchmark for a legend like you to break, ya know. :) 

Good morning FKT world!

I wanted to share I will be attempting to hike the Colorado Trail from Denver to Durango Self- supported, East to west, Collegiate East starting tomorrow 7/21/21 I will hike in a traditional thru-hiker style, have sent myself food, will be on foot the whole time and have no planned help along the way. I will have an Inreach tracking my effort but will keep this private until the end. I will post a few pictures/ videos on my instagram account should you want to follow along. 

Thank you so much to all who have gone for this dream before me and have it as a dream for the future! 

Happy Trails - Early Bird/ Nika Meyers

It's not yet announced, but looks like not only new FKT by a day, but possibly John's time for unsupported is surpassed? I can't wait to hear more!

The "holy cow" was for you, Nika, went in the wrong box. Huge congrats! It was a totally insane time to begin with (or, pun, finish with), and then I read your blog. Sheesh, I am in awe of what you had dealt with, and threw down the time that is nearly identical to female supported and John's unsupported. I thought Mikaela's time was (and it IS) badass to stay for awhile. Ladies keep breaking barriers. Super-crazy. Loved the report. Amazing accomplishment.

Hello! I will be attempting to hike the Colorado Trail from Durango to Denver (West to East, Collegiate East) starting this coming weekend (7/24).  I will be hiking unsupported: carrying all food and gear from the start, no resupply at any point, and no help accepted in any shape or form along the way (no pacers, crew, trail angels, or support from strangers).  I will have a Spot Gen3 tracking device that will be private and made public once I finish.  I will attempt to post pictures and updates on my instagram (@kde_outside) as service allows.

Happy Trails!


Kylee, I am sorry to read you had an injury! You were booking it! Let us know how you're doing, please.

Thanks, Olga! Unfortunately I had to discontinue my hike yesterday at Chalk Creek after some blisters on the bottoms of my feet got progressively worse and impaired my ability to walk.  I think the cause might have been trench foot early on with the wet conditions in the San Juans and long days without fully drying out my feet.  Otherwise my body felt great, so I hope to be back!

Hello beautiful people! I will be setting off for an unsupported FKT tomorrow morning - Denver to Durango, Collegiate East. No pacers, resupply, trail magic, help of any kind. Tracking will be private via Garmin inReach until I finish. Team T-Mobile here, so I'll do my best to update IG with stories along the way @sophrebuilt.

Peace, love, and happy trails!


I left the trail 57 miles in. I thought I could push through despite not having trained like I did last year and Mother Nature kindly humbled me. Hard lesson, but there was no better way for me to learn it.

Much love.

Hello Everyone!

I would like to announce to the FKT world and all you wonderful trail people that on August 1, 2022 I will be setting off to set the self-supported record for the Colorado Trail, West to East, Collegiate West. I will be caching my resupplies in advance, at which I will trade off my supplies to and then go back to pick up upon my completion of the trail. My goal is to complete this route in 11 days, aiming for ~45 miles per day. For my attempt, I am raising money for the American Foundation for Suicide Prevention, as this is a pressing matter in today's society and its impacts are near and dear to my heart. Please read more about my fundraiser here:…. I will be updating on my Instagram @Holly_Proulx as much as feels right when I am out there, and will be tracking with a Garmin inReach. Thank you all for being supportive and inspirational trail dwellers!

Hi there,

I’m getting ready for a self-support FKT attempt on the Colorado Trail, West to East - Collegiate West. I didn’t see any data above for successful FKTs this direction for self-supported on the Collegiate West. Does anybody know what the current FKT is?

It's time to chill, I said a year ago. Yet I can't give up on the dream. Take 2: Colorado Trail, Durango to Denver (NoBo), Collegiate West option. Fully unsupported, solo, female. All rules to follow, details and tracking with officials at FKT. Starting this weekend.

It’s time!

    Tomorrow morning (June 28, 2022) I will be attempting the thru-hiking women's self-supported FKT of the Colorado Trail from Denver to Durango on the East Collegiate route. I’ll be doing the entire trail on foot, and have food cached and prepared for my resupplies along the way. During this process, I’ll be tracking my efforts through Strava and my Garmin in-reach. Stories, moments of triumph and frustration, victories, hunger and photos/videos to come via my Instagram page: @fearlesssarah

Nature, let’s go!!

I'd like to publicly announce that I will be attempting the overall unsupported fkt on the Colorado Trail from Denver to Durango starting Saturday July 16th, 2022.

This will follow a traditional unsupported fkt attempt- 

I will carry everything except water from start to finish. 

I will not accept any trail magic, support, or outside assistance.

I will not be picking up caches or supplies at any point.

I will be on foot the entire time and accept no muleing/pacing etc.

I will be using my inreach mini 2 device and mapshare to to track my location at various times along the way. I will send off a location at night and some point during each day.

I will be posting updates on Instagram if you want to follow along @wandermoreoften

I’m excited to follow behind those who have hiked before me especially those who have set/ attempted the fkt already. This will be my first major backpacking trip and I cannot wait to get out there. Any advice is appreciated/welcomed

Hello Hikers!

I'd like to let everyone know that I am heading out tomorrow morning, attempting to set the self-supported record for the Colorado Trail, West to East, Collegiate East route. I will be caching my resupplies from post offices and stores where I have mailed and sent hiker boxes to. My goal is to complete this route in 13 days. For my attempt, I am raising money for Companeros, a local nonprofit benefiting immigrants in Durango and around the area. (Read more here: I will do my best to keep my instagram @bkristina13 updated and will be tracking with a Garmin inReach. 

Happy Trails!

I’m setting out 8/22/22 to start the self-supported Durango to Denver, Collegiate East route for female. I have mailed and cached my own resupply, will be sharing my Garmin Inreach link. There is currently no self-supported time for female nobo on either route, so I hope to get something on the books to encourage more people to get out there! 
Happy Trails,

Hello fellow FKTers!

I would like to publicly announce that I am going to pursue the women's unsupported FKT on the CO Trail. I will start in Denver on 7/19 and will take the Collegiate West route. I will be tracking using the spot X and have contacted FKT and gave them my tracking link. I will not post my tracking link publicly. I also will wear my garmin fenix 7, which I’ll sync it to Strava when I’m off of the trails. I will take many pictures and will post updates via my Instagram as cell service allows at I will be taking all of my gear and food with me and will not resupply at all. I will not have anyone meeting me along the way. There currently is no unsupported record for women on any of the 4 routes. I will try to beat the current FKT supported record SOBO/east collegiate of 9d 10h 52m and doing so taking the west collegiate section. 

Happy Trails!
