OT: Tough Mudder
You are a better woman/man than me Jules!
There was a girl training for one at my gym and she trained like she was a marine (i.e. the one handed pushups in taebo and everything).
I guess it is a ton of fun if you like dirt and obstacle courses!
I think you should do it. Even finishing it is a huge honor and accomplishment.
