IRONMAN 70.3 Boulder is more than just a "half" IRONMAN. It's a cherished experience at the foot of the Rockies in one of America's hubs for elite athletes.
Nestled at the foot of the stunning 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 make it a favorite on the IRONMAN circuit.
The 70.3 offers athletes the chance to focus on their performance and prep for future full IRONMAN opportunities.

The race will start at the Boulder Reservoir with a single-loop swim. Once finished in the water, the first transition will start the athletes on a beautiful one-loop bike course all contained in Boulder County. It has under 2,000 feet of elevation gain. The two-loop run course is very fast and only has 340 feet of gain. The 13.1-mile route will take you along the Boulder Reservoir, up 51st Street to Monarch, back down 63rd Street and along the Dam Road. Most of the course is on dirt roads.
