I was sitting in my office 2 months ago and noticed 1 of my guys running seldom do I see this so I asked him what he was training for he said it was for a tough mudder competition. He told me about it said it was a 10mile obsticle course. Now I was curious so I logged on to it's website www.toughmudder.com Hmmm I'm ex military so this is right up my alley My question is have any of you done this? If so your thoughts and did cycling play a big role in your training along with running and weight lifting? There are two events in 2012 near my 1 in MN and 1 near Madison, WI Im pumped 48 years old and cant wait to get dirty and bloody lol.
