Nestled at the foot of the Flatirons Mountains, Boulder, Colorado is 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 from the first running.
Boulder's famous pedestrian-only Pearl Street Mall downtown 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 athletes on a beautiful multi-loop course all contained within Boulder County. The course has a few pronounced climbs, but in general it's a fast one. Once done with the two 40+ mile loops, athletes will complete 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 their athletes, and the last few steps of the day happen on Pearl Street, making for a triumphant finish.
