I have allways admired people who can challenge the human body. You must be strong in mind and body. Also you have to make a lot of sacrifices to achieve your goal.
I don't really like to run, but I want to get in shape and can fundraise for my favorite charities. It would be awesome to compete ina marathon in every state(50 state marathon club). I also want to do Warrior Dash and Tough Mudder.
