This Event Took Place Sat. Oct 28, 2023


Tunxis Ultra is part of the Blue Blazed Trail Running Series.

We are once again offering three distances this year: 60K (37.5 miles), 30K (18.75 miles), and 5K (3.1 miles)!

The start times are staggered by distance:

  • 60K starts at 6 AM, which is 20 minutes before dawn, but during civil twilight. Please bring a light in case you decide that you need it.
  • 30K starts at 7 AM.
  • 5K starts at 8 AM.

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), a 60K Ultramarathon, and a 5K "Ultra".

The courses consist of lovely double track, single track, half track, off track, a little bit of road and maybe some prickers, if we don’t get to brush hogging some bits of the trail. The 30K and 60K 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.

The official 30K and 60K course map is on CalTopo.
