@ Farmindale- i hear ya loud and clear. I broke my back a number of times, and had a major accident 4 years ago. mostly metal in my right hip and leg now. I have done six or eight of the mud type races over the last couple years. In training... if i go over the 4 mile mark jogging, bad news. hip and back go into serious shut down.
Now its training everyday with Mountain Tactical plan. if you guys haven't tried them DO IT. Rob Shaul is a program guru and i love his work. Put my own kettlebell program together now and mixing in the back pack work starting THIS WEEK... Bring on CO mountains. i will be fit and ready!!
