Route: Manitou Incline (CO)

Colorado, US
1.1 mi

The Manitou Incline, near Manitou Springs, Colorado, was constructed as a funicular in 1907. It operated until 1990, when a rock slide washed out the rail bed. Since then it has been used for hiking, and has become a very popular test piece for endurance athletes. The Incline starts at 6600 feet elevation and gains 2000 feet in roughly a mile. The old railway ties form many steps along the route. In recent years work has been done to improve the tread and steps, and to make the Incline safer for hikers. has a nice article on the Incline and some of the FKTs.

Official Incline times are simply from the first railroad tie to the last one.  A Strava segment for the ascent is here:

Pro tri-athlete Mark Fretta appears to have a fast time for an ascent of the Incline, at 16m42s, set in 2006. There has been some controversy around this due to Fretta's sanction in 2012 by the US Anti Doping Agency, and whether his time was actually to the top of the Incline. Olympic speed skaters Ryan Bradford and Apolo Ohno also apparently ran the ascent in 17m41s and 17m52s, respectively, on the same day as Fretta, but again there is uncertainty about where exactly these athletes stopped their watches.  Locals do not consider these times valid, so we don't Fretta's time as the FKT.

We have FKTs for the Ascent, the "Inclinathon", which is 13 round-trip laps of the Incline, adding up to about a marathon with an incredible 26,000 feet of vertical gain, for the most laps of the Incline in 24 hours, and for the most ascents in one year. A "lap" of the Incline requires staying on the trail for both the ascent and the descent.

For the "month" variation, current record holders as of September 12, 2023 are Crazy Bob Stuka (male) with 232 laps from October 1-31, 2022 and Rachel Jones (female) with 134 laps from August 20 to September 19, 2022, per records documented on the Facebook page called The Manitou Incline (Official Group). 

Here's a great video about the Incline by Salomon TV:

Lots of locals to not believe Fretta's claim for this FKT.  Seems like it least deserves an asterisk.  See this story for more details.

There is no valid, repeatable reason to disregard the times of Mark Fretta, Ryan Bradford, and Apolo Ohno. They are Olympic athletes and the runs were done in the pre-GPS era. Local runners know Joe Gray and Matt Carpenter, and they are both fantastic runners and inspirational athletes. It's easy to want to disregard the performances of some guys that aren't really runners and aren't part of the local running community. However, do we have any more proof of Matt Carpenter's 18:31 than of the Fretta/Bradford/Ohno trio? No. The times of these three athletes should be listed, without asterisks, same as Matt Carpenter.

If it makes sense to start marking ALL pre-GPS FKTs with an asterisk, then there is a lot of work to do. But Fretta, in 2014, addressed the questions that were raised - including whether or not they started from the bottom step.

Anyone who wishes to erase the Fretta/Bradford/Ohno times from the record book needs to explain why, in terms that can be equally and fairly applied to all FKTs of that timeframe. Otherwise, I think you have to accept the word of three Olympic athletes.

Also, for what it's worth, there is a sign posted at the base of the Incline which notes the fastest time as 16:42.
