Prepare for a true test of grit and spirit at the Traprock 50 & 17K, set for April 18, 2026, in Bloomfield, CT. This iconic event, often dubbed Connecticut's "spring classic" ultra race, challenges runners with its notoriously technical terrain and significant elevation changes. Hosted by the passionate, all-volunteer CT Trailmixers, the race takes place within the scenic Penwood State Park and serves as a key event in the Blue Blazed Trail Running Series. Runners can choose between the demanding 50K, comprising three challenging loops, or the equally engaging 17K single-loop option. Typical race day conditions often feature comfortable highs around 62F and lows near 41F, with a modest 16% chance of precipitation, providing ideal weather for a strenuous trail adventure.

The Traprock course is a demanding, rolling loop of approximately 10.5-11 miles, featuring a significant amount of technical singletrack along the famous Metacomet Trail. Expect a relentless mix of rocks, roots, steep uphills, and exhilarating downhills, with some sections described as akin to "stone stairs cut into a frigging cliff". With the 50K boasting around 3874.5 feet of elevation gain, this course is designed to test both physical fitness and mental fortitude. Beyond the challenge, runners are rewarded with beautiful forest scenery and picturesque views of the surrounding New England landscape from the ridge tops. Aid stations, staffed by "awesome" volunteers, are strategically placed to support runners through each loop, though participants should note this is a cupless race and must bring their own hydration vessels.

Renowned for its strong community atmosphere, the Traprock 50 promises a satisfying and memorable race experience, drawing many runners back year after year. The event kicks off with the 50K at 8:30 AM, followed by the 17K at 9:30 AM, both starting and finishing in Penwood State Park. Race proceeds generously benefit local organizations such as the Simsbury Land Trust and the Connecticut Forest & Parks Association, meaning your effort on the trails also contributes to preserving the beauty you experience. Prepare for an unforgettable day on Connecticut’s rugged trails, where the challenge is as rewarding as the camaraderie.
