So when his brother challenged him to take part in the Escape to Miami triathlon, Matt Damon decided to give it a shot. He was part of a team that included his brother Kyle, stepfather Jay Jones, and friend Barry Hetherington. Matt didn't have to do the whole triathlon, mind you. His portion was a 6.2-mile leg of the road race, which he ran in 59 minutes, 54 seconds. "I knew I was in trouble when the old guy with the oxygen tank passed me," he quipped.

So Matt has a little work left to do, but that's OK. He's putting himself out there and working hard at regaining his fitness. I don't know if I'd be willing to put on weight for a movie role; it seems like it's a lot easier to maintain a healthy weight than to try and lose 20 pounds or more. But then again, if I was earning Matt Damon's salary, I might have to think about it!
