I am impressed by a simple marathon. To me, running 26.2 miles seems like enough of a feat, but plain old marathons pale in comparison to ultramarathons. These endurance races are not only extreme distances, but many take place in extreme locations as well.
I just leaned about the Marathon des Sables, and to be extreme about the race I thought I would ask you a few questions about it. Guessing the answers on this one is half the fun, since you have to think very far outside the box to understand the mind of an endurance racer.
After taking the quiz let me know if you have ever (or have the desire to) run an ultramarathon in the comments section below.
