Jack Bristol Lake Waramaug Ultra Races

The Jack Bristol Lake Waramaug Ultra Races, taking place on April 27, 2025, marks the 51st anniversary of this historic event, recognized as the oldest ultras in Connecticut and the first 100K in the United States. Participants can choose from three distances: 100K, 50 miles, and 50K, all set on a scenic, primarily flat course around Lake Waramaug. The event features well-stocked aid stations, post-race food, and custom medals and buckles for finishers.
