Vic:
I've been doing crossfit and "crossfit on steroids" since November. Good stuff, mostly based on Charles Poloquin's approach as my trainer is a Poloquin disciple. Olympic lifts play a big part of every workout, along with alot of form work, pullups, pushups, sled drags, etc.
I can't run to save my life as it kills my knees, but can complete a 5K in about 22-23 minutes or so. The tough mudder looks to a different beast altogether as its 12 miles up and down Mt. Snow through 30 or so obstacles. Seems to be the granddaddy of all obstacle races. I'll let you know how it goes...they make you sign a death waiver and life insurance policy just in case...
