Event details

The Traprock 17 and 50K trail races take place on Saturday, April 18, 2026, at Penwood State Park in Bloomfield, Connecticut. Distances offered:

  • 50K
  • 17K

The 17K uses one loop of the course and the 50K uses three loops. Registration opens November 27, 2025. Once the race reaches capacity, a waitlist opens; entrants are selected from the waitlist in registration order and selected entrants have two days to respond.

Course and race policies

The loop is approximately 10.5 to 11 miles per loop. The course is rolling and consists of about 50% technical single track on the Metacomet Trail, with the balance on double-track and forest roads. Sections can be extremely rocky. A specific power line hill remains on the course. The 50K has a nine hour cutoff.

The event is cupless; participants should bring their own cup or handheld bottle. Chip timing will be used in 2026. Shirts are available for separate purchase in the event store; the logo is to be determined. The race is organized by the CT Trailmixers, a volunteer non-profit club. Race proceeds will support local organizations including the Simsbury Land Trust and the Connecticut Forest & Parks Association. Refund policy: cancellations before March 1 receive a 50% refund; no refunds, bib transfers, or deferrals after that date. Visit the organization's website for the most recent information.
