Clayton Treska, 30, is battling stage 4 testicular cancer, but that didn't stop him from tackling the grueling event coming up in Hawaii — his first triathlon. The Iraq war vet is planning on college too.
The 1,800 competitors in the 2010 Ford Ironman World Championship thisweekend in Hawaii will battle the surf (for a 2.4-mile swim), the island's uphill roads (for the 112-mile bike ride) and the rocky terrain (for a 26.2-mile marathon run).
