I think Ryan Reynolds might be a bit of a liar. After insisting that he's not a runner and that he'd be lucky to cross the finish line in last weekend's New York City Marathon, Ryan completed the 26.2 mile run in three hours and 50 minutes, which comes out to around a 8:45 mile (if my math is correct).

At the finish line, he told reporters that he was pretty excited to still be standing and explained that seeing Michael J. Fox around mile 20 caused him "to gain about 15 pounds in goosebumps" and gave him the motivation to push through the last few miles. He ran as a part of Team Fox in honor of his father, who suffers from Parkinson's Disease and raised over $80,000 in contributions for the cause.

"I thought a lot about my father and Michael and the 500,000 other people afflicted with this awful disease in the United States alone," Ryan explained, adding, "I ran for those who can't."

This guy is every bit my idea of a Fit Celeb -- his mind, heart, and body are all in good shape. However, don't expect to see Ryan do it again any time soon. He has been quoted as saying, "I would sooner be prime minister of the moon than run another marathon."
