Event Description

Hosted by a town many pro triathletes call home base throughout the year, IRONMAN Boulder showcases a beautiful course and location.

Nestled at the foot of the imposing Flatirons, Boulder, Colorado is already a wildly popular home-base and vacation destination for triathletes. The city's health-conscious culture, near-perfect weather and breathtaking natural environment made it an instant favorite when it debuted last year.

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.

Once finished in the water, the first transition will start the athletes on a beautiful multi-loop course all contained in Boulder County. The course has a few pronounced climbs in it, but in general it plays out very fast. Once done with the two 40+ mile loops you will do the final 85-112 miles on an additional loop and roll into Downtown Boulder for the second transition 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.
