The WEC events last two days and venture through all types of terrain including logs, rocks, mud, and water. They have three or four different types of tests on a lap and have to do each of them twice in a day. Each test is timed and the one with the lowest overall time is the winner. Plus, at the end of day one, they get 15 minutes---yes, 15--to change both tires and do any maintenance on their bike that is necessary...that's it! They're gnarly. The starwars music ending the GP AMV of Spain video makes it even cooler!
