About 90% of this trail shares dirt with the Pachaug motorcycle enduro route. There's lots of jeep road, but the kind of jeep road that requires an off-road jeep, not your neighbor's drive to the grocery store jeep. In the fall, loose rocks ranging from the size of golf balls to softballs will hide under massive piles of oak leaves where they wait to take you down. On the few sections of single track, the rocks are embedded firmly in the ground, but along with the roots, this terrain isn't much easier. Spring might seem like a better time to enjoy this route. That might be the case if you like wet feet. This trail hits some low spots that are often flooded following a snowy winter. Oh, winter? That might be a good time to do this, but you will might find everything described above with the added challenge of snow and ice. Summer then... well, early summer brings deer flies, and later summer brings mosquitos that may or may not infect you with Eastern Equine Encephalitis. Choose your poison, and enjoy the route (but you probably won't)!
Admin note: We updated the GPX - thanks to Rob ONeil for figuring this out. See also Lee-Stuart Evans' trail guide: https://theairlandandsea.com/2020/05/the-quinebaug-trail-guide.html The southern end of the trail seems to be at its junction with the Nehantic Trail. Since this is an out & back FKT, we suggest starting at the northern end, and turning around at when you hit the Nehantic Trail. Liz's original GPX had some other errors, as detailed in the Comments below. Note that Evans does not recommend this trail: "The Quinebaug Trail is ... disappointing in almost every way. The nearby Pachaug, Narrangansett and Nehantic should always be a preference to this one."
On the website for the Connecticut Forest & Park Association (CFPA), it has the southern end of the trail crossing Breakneck Hill Road and continuing on until it meets the Nehantic Trail and gives the one-way length as 8.1 miles. Liz I see on the map you highlighted it shows it ending at Breakneck Hill - just curious which is more up to date, the map or the website.
Also a quick note - looking at the GPX file posted for this route, it goes off trail and is following some of the other roads including Trail 1 Road instead of the blue blazed Quinebaug trail.
In addition, researching on the CFPA's website a little more, they added a note on the trail map indicating that the trail was extended with a new connector to the Nehantic Trail on 10/23/2017. So the full trail now extends to the Nehantic Trail, instead of the southern end being at Breakneck Hill Road.
I ran a portion of the trail on 10-25-2020 (the day after the Pachaug 2020 trail race). The race route followed the blue blazed Quinebaug trail from Breakneck Hill road up to Hell Hollow Road (strava link - https://www.strava.com/activities/4242809862 or from the race, another participant their strava link: https://www.strava.com/activities/4237854763/overview)
Comparing my GPX file against the CFPA website for the trail, my route matches the CFPA trail (https://www.ctwoodlands.org/blue-blazed-hiking-trails/blue-blazed-hikin…). However comparing my route against the GPX file listed above [Quinebaug Trail (out and back).gpx], the person who was hiking the trail instead followed the road and not the blue blazes for a significant portion of the route up to Hell Hollow Road.
Thanks for the heads up! I updated the GPX and route info as discussed in the Admin Note above.
Wow Peter, I'm really impressed with how quickly you reviewed and updated that.
The new link is "mostly" right. I ran the course today and started to do the same mistake they did, but managed to correct myself. I can submit a corrected GPX file with my FKT submission (along with my original GPX file) - this way folks can see where the blue blazed trail goes. Its tricky in one section since it looks like a tree with a blue blaze at an intersection fell down. You can easily see the correct route easily when running northbound, but southbound its harder to see that you need to take a right. Also the trail isn't horrible...it just has some harder parts in the middle...say miles 2 to 6. But the first and last miles of the 8 mile trail are nice...as are a few bits in the middle. The hard parts are where you run on a path shared with the Enduro motorcycle trail - rocky and loose sand in some sections.
