The Tunxis Trail Ultramarathon is a challenging, technical trail race through the Tunxis Trail system in Burlington, CT. The Tunxis Trail is part of the Blue Blazed hiking trail system managed by Connecticut Forest and Parks Association. We, the Burlington Land Trust, is holding the race as a fundraiser. There are options for an 30K mile “fun run” (in honor of the Barkley Marathons) and a 60K Ultramarathon. This year’s inaugural race starts at 6 am on August 25th, 2018. The course is a Figure-8 over 30K.

The course consists of lovely double track, single track, half track, off track, a little bit of road (because that’s how CFPA rolls around here) and maybe some prickers, if we don’t get to brush hogging some bits of the trail. This course takes you to all of the “world famous” landmarks of Burlington trails: Sessions Woods, Mile of Ledges, Tory Den, Johnnycake Mountain, the CT State Trout Hatchery, Perry’s Lookout, Nassahegan State Forest, and Devil’s Kitchen.
