Because I'm seriously considering running for 13 miles non-stop. It's insane, and yet, the temptation is so real, just to say "Yeah, I ran a half marathon." Yep, half and half only. I've not totally lost it. This is just a moment of temporary insanity. And one that I am completely committed to--I think. (That doesn't sound complete, does it.) Anyway, if anyone has any advice, post away! I'm going to need it!
