2027 Colorado Triathlon Race Calendar

Explore Colorado’s 2027 triathlon season, from winter multisport and first-time-friendly events to road, gravel, off-road, youth, and long-course racing. Use the calendar to find official event details, discover new race formats, and plan your next start line.

Date status: Race dates, routes, registration availability, and event formats are set by each independent organizer and may change. Events marked “Date to be announced” have a planned month based on their recent calendar pattern, but do not yet have an official 2027 race date. Always confirm details with the event organizer before registering or traveling.
