Messier, a former NHL hockey player, ran the NYC marathon to raise money for two charities - Tomorrow's Children's Fund and Answer the Call, which supports the surviving families of 9/11 first responders. Messier was so exhausted and dizzy after he crossed the finish line, he was put in a wheelchair and shuttled to a medical tent. He recovered quickly after taking in some fluids.

I have to give it to music mogul Sean "P. Diddy" Combs. He trained for only about two months, was running on a bum knee, and still managed to pull out a sub-4:15 marathon. He also raised $2 million for children's charities and New York City public schools in the process.

He took his time in the 2002 Boston Marathon, but the former Saved By the Bell star and host of the Extra TV show really picked up the pace for the 2011 New York City Marathon, as he cruised to a 4:23 finish.

One of the most common questions I hear from marathoners in regards to their goal times is, "What do I have to run to beat Oprah's time?" or "I want to beat Oprah!" Going sub-4:30 is a popular goal time for marathoners anyway, but knowing that they beat Oprah's marathon time is usually icing on the cake for people who reach that goal.
Al Gore, 1997 Marine Corps Marathon (4:54:25)
If you're hoping to beat a politician's time and think Bush and Palin's marks are a little out of your league, Al Gore's time is a lot more achievable.

Subway pitchman Jared Fogle, who famously lost 245 pounds by eating Subway sandwiches, trained for almost a year in preparation for the New York City Marathon. Clad in a black Subway T-shirt, he charmed the marathon crowds on the streets of New York and passed several Subway restaurants without stopping for one of those subs.

I was at the New York City marathon the year Katie Holmes ran it and it was frustrating that there seemed to more buzz among the spectators about her than the elite runners. But I was impressed that she didn't run with a big fancy entourage of security guards and trainers. And those pictures of her stopping to see hubby Tom Cruise and their daughter, Suri, around mile 23 were sweet.

Former Today show co-anchor Meredith Vieira had said she always wanted to run a marathon, but it was colleague Al Roker who inspired her to finally take on the challenge. They were together in the beginning, but Vieira pushed ahead, finishing an hour and 10 minutes before Roker. She was totally giddy wearing her medal on television the next morning.

show weatherman and co-anchor Al Roker had perfect marathon weather as he ran (and walked) through New York City's five boroughs. It was almost dark when he crossed the finish line, but he was all smiles as he was greeted by his family.
