One of triathlon's pioneers, Russ Jones, continues to push himself to victories almost four decades after his first race

Russ Jones is one of triathlon's pioneers, having won the second tri ever held, on San Diego's Mission Bay in 1975. Almost 40 years later, Jones continues to roll on. He's one of just four athletes to ever complete 500 or more triathlons and has done more than 1,000 triathlons, duathlons and road races.
