What if you temporarily took leave from the safety of everyday life to battle through a challenge that scares you? What if your only worries were riding, finding food and water and a place to sneak a few hours of sleep? What if you forgot your self-imposed limits just to see what you were truly capable of for once? What if you were a racer at heart? Why wouldn't you want to take on the toughest races on the planet?
