Stagecoach Gravel Triathlon

August 3rd, 2025 Sprint Distance Triathlon, Aquabike, Stand-Up Paddle-Board Options, & NEW Duathlon ​ ​To say this race is “novel” would be an understatement! Limited to just 250 athletes, we're excited to bring you one of the first ever gravel triathlons to the Colorado triathlon landscape! This event is set at Stagecoach Reservoir, a quiet and picturesque lake just 15min south of Steamboat Springs, with camping options for the entire family. After the swim in the waters of Stagecoach Reservoir, it’s time to bring out either the gravel bike, road bike, or mountain bike. Just leave your triathlon bike at home. The bike course features rolling gravel country roads through some of the most scenic terrain imaginable and is 100% on gravel. The total bike distance is 17 miles! Once off your bike of choice, it’s time to toss on those running shoes for a 4-mile run on a gravel trail that hugs the shoreline of Stagecoach Reservoir! Come join us for this one of a kind triathlon experience, complete with a stand-up paddle-board option for the non-swimmers!
