Join the celebration of tradition at the Jack Bristol Lake Waramaug Ultra Races, renowned as Connecticut's oldest ultra event and the first 100K in the U.S. The race features gently rolling loops primarily on flat, paved roads surrounding the picturesque Lake Waramaug, making it a prime course for personal bests. Participants in the 50K will tackle three laps around the lake, while the 50-mile and 100K runners will complete six and seven laps, respectively, before finishing with an out-and-back segment to the State Park. Time limits for the races vary, with a focus on ensuring every runner's safety and realistic finish times.
