Lory Off-Road Triathlon

Saturday June 20th, 2026 ​ ​The Lory Off-Road Triathlon on June 20th 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 Lory Off-Road 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 2011-2023 in early April! BACK FOR 2024: Stand Up Paddleboard Option instead of the 1/2 mile swim (you must bring your own SUP)!
