Oct 21, 2002 — Over the weekend, three North Country athletes raced in Hawaii's 140-mile Ironman triathlon, the sport's world championship. 55 locals competed this summer in the Lake Placid Ironman. The sport's popularity continues to grow, attracting corporate sponsors and TV contracts. But some critics say more should be done to protect amateur athletes. As Brian Mann reports, a third of those who compete, wind up ill or in the hospital.
