Sleeping Giant Trail Runs

Hamden, United States • 29 Mar 2026

Sleeping Giant Trail Runs, hosted by Steep Endurance at Sleeping Giant State Park in Hamden, CT, offers challenging 25K and 50K trail races through Connecticut’s iconic park. The 25K loop features more than 3,000 feet of vertical gain across rocky and rolling singletrack via Yellow, Chestnut, White, and Quinnipiac (Blue) trails, cresting at the Observation Tower before a descent back to the pavilion. The 50K doubles the challenge with two loops. The course spans 30+ miles of park trails, from smooth carriage roads to technical terrain. Notable features include a cup-less policy, a finisher medal, sponsor swag, post-race food and drinks, and support for the Sleeping Giant Park Association.
