Event overview
Traprock 50 takes place in Bloomfield, Connecticut, at Penwood State Park on Saturday, April 18, 2026. The event offers two race distances:
- 17K
- 50K
Registration opens November 27, 2025. The race is part of the Blue-Blazed Trail Running Series for 2026.
Course and logistics
The course is a loop of approximately 10.5 to 11 miles per loop. The 17K uses one loop and the 50K uses three loops. The route follows the Metacomet Trail for about half its length, with the rest on double-track; much of the single track is technical and can be extremely rocky. Organizers state there will be no changes to the course and that the power line hill remains.
The event is organized by the CT Trailmixers, a volunteer non-profit club. The 50K has a nine-hour cutoff. The race is cupless; participants must provide their own cup or bottle. Chip timing will be used in 2026. Shirts are available for separate purchase. When the race reaches capacity a waitlist opens; waitlist selections follow registration order and selected runners have two days to accept. Refund policy: 50% refund if cancelled before March 1; no refunds after that date. No bib transfers and no deferrals. Race proceeds support local organizations, including the Simsbury Land Trust and the Connecticut Forest & Parks Association. Visit the organization's website for the most recent information.
