Victoria Beckham, marathon mama?

Is Victoria Beckham planning to run the New York City marathon this weekend? We know Posh has taken up running, but reports are coming out that she's actually been training for months in secret (just like her best gal pal, Katie Holmes did last year) and intends to run the race if she's ready. If she's not, she'll put it off until next February and take part in the Los Angeles marathon instead.

There's no doubt she's got some strong legs -- have you seen the insane high heels that woman wears? She walks in them as easily as I walk in my Chuck Taylors. But really? A marathon for Victoria Beckham, who once proclaimed she didn't work out because she didn't like wearing anything but heels?

If she participates, she certainly won't be the first celeb to become a marathoner. Check out the gallery for a few famous faces who've completed 26.2 miles.
