it's definitely the most fun training i've ever done... it SHOULD keep you away from any injuries.
I was talking about Leadman with Todd on Sunday. I like the idea but not the execution. Primarily I'm not a fan of the bike course. If I'm gonna spend that much on racing I'd rather do Breck Epic. I want to ride chunky stuff on tight mountain singletrack!
Break Epic is an awesome one and is on my list for sure.
