Sweltering Summer Ultra

The Sweltering Summer Ultra is an annual running event held at Clapp Park in Pittsfield, Massachusetts. The 13th edition features an 8-hour race on a certified 0.355-mile dirt and cinder track, with runners switching directions halfway through. Participants can run or walk as many laps as they choose, with chip timing and a live leaderboard provided.

The event includes a well-organized aid station with a no-contact bottle refill system, prepackaged snacks, ice pops, and pizza. A virtual 12-hour option is also available to support the AYJ Fund, benefiting children with cancer. Awards are given for overall and age group winners, and the race is part of the BURCS BADASS series. Visit the organization's website for the most recent information.
