XTERRA Lory Triathlon on June 18th is the perfect kick-off to the year for the seasoned off-road triathlete, or a great opportunity for the road triathlete wanting to try out a mountain bike triathlon for the first time.
The XTERRA Lory Triathlon features a 1/2 mile swim in the clear waters of Horsetooth Reservoir (Eltuk Bay), it’s one of the most scenic swims in the state with canyon walls on both sides. Then it’s on to a 2-Lap (beginner friendly) 12.2 mile single-track bike over rolling terrain, and across valley bridges at Lory State Park. Then you’ll get to finish things off with a fun and challenging 4.8 mile (8k) run through the clouds on single-track trails! This is the perfect off-road triathlon for beginners to experts. The course is designed so that anyone can have fun and everyone will be challenged! Entries will be limited to 350 participants, and we sold out 2011-2021 in early April!
BACK FOR 2022: Stand Up Paddleboard Option instead of the 1/2 mile swim (you must bring your own SUP)!

Are you looking for a new challenge this summer? Register for the 8th Annual Frisco Triathlon featuring stand-up-paddle boarding, mountain biking, and trail running. This twist on a triathlon is open to all ability levels and encourages athletes to take on a new multi-sport event. The Frisco Triathlon was named “Best Triathlon” in Elevation Outdoors Magazine’s reader poll, 2016 Best of the Rockies.
The Frisco Triathlon will be held on a Friday; with the volume of people we see at the Frisco Bay Marina on the weekends, we feel that we can provide the best racer experience, as well as provide a safe environment for other Marina guests by holding the race to a Friday.

Stagecoach Gravel Triathlon

We didn’t get the chance to launch this race in 2020, but that didn’t diminish our passion for this brand new style of triathlon! To say this race is “unique” would be an understatement! Limited to just 250 athletes, we’re excited to announce the first ever gravel triathlon 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 course starts out with a short-paved section of 2.1 miles, before transitioning to rolling gravel country roads through some of the most scenic terrain imaginable. The total bike distance is 16 miles, with the final 3 miles of the course on pavement as athletes head back towards the transition area! 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, (Note: ½ mile total on paved roads)! Come join us for this one of a kind triathlon experience, complete with a stand-up paddle-board option for the non-swimmers!
