Atomic Man Duathlon

The Atomic Man is a duathlon, where participants start with a run, then bike, and finish with another run. More details coming soon for our 2019 race in the coming month, so save the date!

Our Sponsors


All proceeds benefit local athletic programs!

We are proud to announce a portion of the proceeds will go to support underprivileged cross country runners in northern New Mexico! Many of our local communities cannot afford to send their children to athletic events (e.g. traveling to Albuquerque) or decent running shoes. One of our beneficiaries will be the Coronado Cross Country Team, who do not have their own uniforms when competing at meets. We hope that the Atomic Man can help children continue their love of running, biking, and other sports.

Registrants may also donate an additional amount to this cause in the donation box. Los Alamos Triatomics (the hosting organization for the Atomic Man Duathlon) is a 501c3 organization and donations are tax deductible. ONLY THE ADDITIONAL DONATION AMOUNT, NOT THE RACE REGISTRATION, IS ELIGIBLE FOR TAX DEDUCTION.
