Boulder Sunset Tri/Du/Run

The Boulder Sunset has grown to be one of the local favorites, due to its later start and warmer water temperatures. With a Sprint, Olympic, Duathlon and 5K run, this nonprofit event attracts the entire community for one unforgettable day. The Sunset is the perfect race for the seasoned triathlete and newbie alike. Our swim support, smaller waves, and course markings will make for a safe, epic and stress-free race experience. The course is the same as the Boulder Sunrise, which gives each athlete the chance to beat their previous time and win the Double Dare Challenge. 

Boulder Sunset will take place at the Boulder Reservoir. The late season and later start time make your morning and swim just that much better! The scenic bike course along the foothills is fast and fun. Taking place on some of the best roads in Boulder. Finish your race on a beautiful dirt road along the Boulder Reservoir and then enjoy a complementary ice cold beer and post-race race meal at the expo!
