Armstrong is banned from events that follow World Anti-Doping Agency rules after he chose not to fight USADA charges of doping.

Armstrong finished the 70-mile swim, bike and run in 4 hours, 16 minutes at the Revolution3 Half-Full Triathlon on Sunday, racing in a wave of fellow cancer survivors.

Brock Yetso, president of the Ulman Cancer Fund for Young Adults, says “it was an easy decision” to allow Armstrong to participate because the event raises money for cancer.

Livestrong CEO Doug Ulman founded the Ulman Cancer Foundation. Armstrong says Ulman led Livestrong “to where it is today.”

Yetso says only two people decided to drop out of the triathlon after sanctioning was dropped, while 300 said they wanted to race because of the decision.
