Guess all those on-set photos of Matt Damon looking less than fit finally got to him. The actor, who packed on the pounds for his upcoming film The Informant, finished the running portion of Florida's Escape to Miami with his team of stepfather Jay Jones and family friend Barry Hetherington. Matt said his brother convinced him to do the race in an effort to get in shape for his next film, but he's got some catching up to do. "I knew I was in trouble when the old guy with the oxygen tank passed me," he joked. His stepfather added that Matt was the "team's weakest link." Matt, on a relay team, finished the 6.2-mile leg in 59:54.
