IRONMAN Boulder returns this weekend: the super triathlon favorite in the heart of America’s most triathlon-centric town.

The two races on Sunday, June 9 rely on nearly 4,000 volunteers to make it happen! That’s one volunteer for every athlete. Want to help? The IRONMAN Foundation Volunteer Program creates positive, tangible change in race communities with grant funding and volunteerism. This is your chance to get involved and support your greater Boulder community with volunteerism.

Join other volunteers on the racecourse, at the finish line or at the expo. Volunteer Captains are still needed as well (no experience required, but you’ll have a higher level of responsibility). Volunteers (age 16 and over, please) are required to register at

The 2019 IRONMAN 70.3 Boulder will offer 30 qualifying slots to the 2020 IRONMAN 70.3 World Championship in, Taupõ, New Zealand. Ironman Boulder is an amazing event. So come out­—and help out.
