I did last year's Tough Mudder Mid-Atlantic at Frederick, MD (Side story, was a HUGE debacle...ended up getting cancelled due to rain early on Saturday and both the parking and track were such a mess they cancelled Sunday too, leading to scheduling this weekend's one in Spring). I don't plan to do anymore, but it was a great training experience and a hell of a lot of fun, through a hell of a lot of pain.

Saw this on BR.com. John, Juan, Kevin Byrne, spouses, and a few other people did this as a team. Reason #182351 I love our coach. Look at his face on these pics, he was having a BLAST. There are a good amount of HC in the NFL I can't see doing this kind of thing.
