I've been asked to do this ultimate obstacle course with a group of mainly military friends but there will be a couple of us who have never served.
http://toughmudder.com/about/I'm getting on in years now (38) and I've never thought a marathon was worthwhile or interesting so this would be a great way to focus on an ultimate physical/mental challenge before 40...
My personal cardio start point is low, personal strength high but as we have a years training to get ready I think I'm gonna do it.



Have any of you done marathons / iron man type stuff?
Any tips?
It was either this or take up an offer of a full scholarship to an Al Qaeda training camp but this one has FREE BEER at the end, so is more in line with my religious values.. :P
