Ironman 70.3 Boulder

Athletes will begin with a 1.2-mile, one-loop swim in the Boulder Reservoir followed by a 56-mile relatively flat bike course with slight inclines and descents. The 13.1-mile, two-loop run course offers great views of the Rocky Mountains and allows spectators to cheer athletes on as they head to the finish line.

Ironman 70.3 Boulder takes place in Boulder, Colorado, located about 30 miles northwest of Denver. Because of its natural surroundings, Boulder is the perfect place for outdoor recreation and the race offers spectacular views of the Rocky Mountains to athletes and spectators.
