Urbanathlon.

Suzi has convinced me, yet again, to do another challenge: The Men's Health Urbanathlon. It's a nine mile race with obstacles every few miles. A few of the obstacles are monkey bars and going up and down the stairs at Soldier Field. Here's the full list. Even though the challenges seem like fun now, I'm sure I'll be kicking myself for signing up for this while I'm crawling under a cargo net or scaling an 8 or 9 foot wall. Anyone else looking for a challenge?
