Some athletic feats are so mind boggling that it's hard to actually understand their significance.
Triathlons are a perfect example. Take the granddaddy of triathlons, the Ironman Triathlon. It's tough for many of us to grasp the concept of swimming in open water for 2.4 miles, riding a bike for 112 miles and then running a 26.2 mile marathon all within a ten to 15 hour time period. PRO aquatics director Don Burton, who has competed in four Ironman events, has another way of looking at it. And then keep in mind that the serious competitors finish in under 10 hours.
