I know a lot of folks who do these, they look like a lot of fun but certainly challenging. One of my coworkers sent me a picture of him running through a fire and into ice water...might have been a different event but there are a handful o them. I'll stay on my bike personally, got a 100 miler that I'm training for at the moment.
