Race Day at Ironman Hawaii 2011

As usual, Andy Potts was the first guy out of the water. Behind him, a huge chase group was riding hard to catch and overtake him. To no one's surprise, Lieto and Tollakson were at the front pushing the pace.

This year, the Ironman World Championships proved to be one of the most exciting in recent memory. Craig Alexander transformed into a super-biker, posting the fifth fastest bike split in the race's history! And Chrissie Wellington showed the depth of her fortitude by overcoming a 22-minute deficit to take her fourth title in four attempts. And in the midst of that story is some of the most amazing, high-tech gear the sport has ever seen. Here's a gallery of some of the best biking and running shots we took from the day.
