Biggest Loser contestants to run Boston Marathon

BOSTON -- Patrick House won big this year on The Biggest Loser.

"This time last year, I was unemployed and 421 pounds and nowhere near doing a marathon, so it's been quite a turnaround," he said.

Patrick lost 181 pounds on the show, earning him the title of "The Biggest Loser".

"If you'd have told me last year, in 2011 you're gonna run a marathon, I would have laughed in your face and probably hurt myself falling on the ground," he said.

But he is going to run a marathon, and not just for himself. He's raising money for two charities.

Inspired by his brother-in-law, who was hospitalized for liver problems, Patrick is raising money for the American Liver Foundation. And until the big day, he's matching every dollar donated with another dollar to "Wounded Warriors,” in honor of a classmate who was killed in action overseas.

But he's not the only "Biggest Loser" graduate hitting the road Monday.

"We're not doing it to set records; we're doing it to raise money. Myself, I'm doing it for Children’s Hospital in Boston," Brendan Donovan said.

A Massachusetts native, Donovan is joining Patrick in Monday's run. He stopped by the hospital for some pre-race inspiration.

"I'm scared, but you know, when I see the kids today at the hospital, it's gonna make me want to finish,” he said. “I'll think of them when I want to quit at mile 16, heartbreak hill, or Boston College. I'm going to think of the kids at Children's Hospital."

Patrick and Brendan will be running together along with two other “Biggest Loser” contestants from season 10.

They may be raising money for different charities, but they plan to cheer each other on to the finish.
