Completing an Ironman triathlon—a race consisting of a 2.4-mile swim, a 112-mile bicycle ride and a 26.2-mile run—is an unfathomable task for most people.

But for Dave Tolbert, a senior corporate risk manager in the Denver Design Center, the Ironman is more than a personal challenge—it’s a way to make a difference.

Tolbert and his wife Marianne, who have completed two and five Ironman triathlons respectively, are both members of the IRONMAN Foundation Newton Running Ambassador Triathlon Team, a group of athletes from across the country who combine their love of triathlons with their passion for community service. The team exists to benefit the communities where Ironman events take place through volunteer projects and fundraising. That’s the basis for the team’s informal name, team “kokua,” a Hawaiian word that means to give to others solely for their benefit. Hundreds of applications for the team are submitted each year, but only 40 people are selected.

This is the Tolberts’ second year on the team. As ambassadors, they have committed to participating in one, half-Ironman distance event and two full Ironman distance events this year, while also supporting non-profit groups in communities that host events. Their efforts reflect Zachry’s encouragement of active lifestyles and also align with the company’s concept of Corporate Citizenship, which includes an emphasis on community investment and philanthropy.
