It's kind of hard to explain...so you will just have to go read it for yourself, but the gist is that Mark, aka the running blogfather, is willing to don a running skirt (and possibly the matching bra, although that is up in the air at the moment), and actually compete in it, if YOU all will donate to the charity of your choice.
Like I said, you kind of have to read it.
I'm all for men in skirts! So, go support Mark right now. He's doing this to raise money for charity (he says) and to get more running chicks into running skirts. Sort of a sacrifice on his part for all mankind.
It just doesn't get better than this, people.
