I'm not sure how many of you knew this, but Will Ferrell has been running marathons for the past few years:

"Will Ferrell, famous for Saturday nights in New York, will be joining the field for Monday afternoon's race in Boston.

Ferrell, known for his work on "Saturday Night Live," and his wife, Viveca, will race in their third major marathon.

The Ferrells ran the 2001 New York Marathon and both finished in 5:01:56. Last June, they ran the Stockholm Marathon and finished in 4:28:02. Will ran a 1:45:02 half-marathon in November.

Ferrell has been training under coach Gary Kobat and has lost 25 pounds. The actor recently told Runner's World that his hard work has certainly paid off. "Whenever I see an old friend or cast member, they say 'Wow, you look great.' And I feel great, too. I have more energy, and I've found that my increased fitness makes me feel better about myself in an overall sense.""

I mention this because he has a new movie coming out (actually about 10 movies coming out), Kicking and Screaming, where he looks so skinny. It's amazing.
