One of the world’s most popular triathlon destinations, this beloved Rocky Mountain town now hosts a full-distance race. Welcome to IRONMAN Boulder.
Nestled at the foot of the imposing Flatirons, Boulder, Colorado is already a wildly popular home-base and vacation destination for world-class triathletes. The city’s health-conscious culture, near-perfect weather and breathtaking natural environment means it’s destined to be an instant favorite on the IRONMAN circuit.
Boulder’s robust downtown, with its famous pedestrian-only Pearl Street Mall and idyllic Boulder Creek, will provide families and fans an unforgettable race day as they wait for their loved ones to cross the finish line. From five-star hotels to James Beard award-winning restaurants, Boulder’s hotel and dining options are some of the best in the nation.
The race will start at the Boulder Reservoir with a single loop 2.4-mile swim. Once finished in the water, the first transition will start the athletes on a beautiful 112-mile one-loop bike course in the city’s vast open space. The bike will loop around Carter Lake and along the eastern plains of the Front Range before ending downtown at Boulder High School.
The two-loop run course is almost entirely on Boulder Creek Trail, winding along the creek and through city parks. Spectators will have multiple opportunities to cheer on the athletes and the last few steps of the day will take athletes up Pearl Street for a triumphant finish.
Can’t wait to get there? Come and race the Boulder Sprint Triathlon or the Boulder Peak Triathlon to see what the area is like and for a true taste of the region before coming back in August for the inaugural full distance race!
