Matt Damon did his bit for the Escape To Miami Triathlon on Sunday morning, the Miami Herald reported.
The Bourne Ultimatum star said that he had competed in the triathlon at his brother Kyles request.
“I knew I was in trouble when the old guy with the oxygen tank passed me,” he said.
Damon completed the 6.2 mile challenge in 59 minutes and 54 seconds, and did add that he struggled a bit because he was carrying extra weight for a film role.
“I was doing this movie this summer, The Informant, where I had to put on all this weight, and my brother told me, ‘October 5, save the date’,” he explained.
