This past weekend, I competed in this event with a bunch of other CrossFitters. It was brutal, to say the least. It was fun to be able to push myself and see everyone else do the same. I ended up competing in this event on a week's notice, but I ended up in 9th place with a final time of 1:41:36, so that's not too bad. Over an hour and a half of pain. Take a look at the workout and give it a try, if you like. If you need to see any of the exercises, here's a video of the movement standards.
Have fun with it and... and try not to die!
