Harvest Moon Triathlon 2027
The Harvest Moon event takes place at Boulder Reservoir in Colorado on September 12, 2027. The centerpiece is the Half Distance triathlon, held as part of a multi-discipline race day that combines open-water swim, bike, and run segments.
The event offers multiple race options for individual athletes and relay teams, including Olympic and sprint triathlons, long and Olympic aquabike races, and long and Olympic duathlons. Relay entries are available for the long course triathlon with designated captain and team member roles. Entry categories and fees vary by race type.
Established in 2000, the event is presented as a long-running local triathlon with participants ranging from experienced competitors to those new to multi-sport racing. The organizer emphasizes athlete safety and local race character. The aquabike competition is described by the organizer as a rapidly growing part of the event, and the duathlon is presented as Colorado's only long-course duathlon.
Racing takes place around the reservoir and on nearby roads and paths. Logistics such as transitions, course layouts, and participant services are provided by the race crew on site. Visit the organization's website for the most recent information.
