Traprock 50 - Penwood State Park
The event is a trail running day at Penwood State Park in Bloomfield, CT, organized by the CT Trailmixers, a volunteer non-profit trail running club. Distances offered are listed below.
- 50K : three loops (approx 10.5 to 11 miles per loop)
- 17K : one loop (approx 10.5 to 11 miles)
The course is a looped format on the Metacomet Trail and adjacent paths. About half the route is technical single track and the remainder is double-track or rolling forest roads. Sections of single track can be extremely rocky. The course will include a notable power line hill and no course changes are planned.
Entry guidance notes that runners should have recent road or trail marathon experience before attempting the event. The 50K has a nine hour cutoff. The race operates cupless; participants must provide their own cup or handheld bottle. Chip timing will be used for the 2026 event. A quality tech shirt is available for separate purchase.
When the event reaches capacity a waitlist opens; entrants are selected from the waitlist in registration order and have two days to accept placement. Refund and transfer policy: 50% refund if canceled before March 1, no refunds after, and no bib transfers or deferrals. Race proceeds benefit local organizations including land trusts and forest and parks groups. Visit the organization's website for the most recent information.
