Well isn't this site just terrible or what. But here it goes.
I've been crossfitting for over 2 years. Had to take a 6 month break after I broke my hands.
I've done a ton of obstacle races, and the best has to be Spartan Races and Goruck Challenges. I've competed in over 3 dozen Spartans and a dozen Goruck Challenges, the longest being 50 hours. I have traveled from Hawaii to Aruba to the Bahamas, and I'll get on a plane tomorrow to go anywhere.
Lets grab a drink, plan a trip and go!
