What obstacles would be included in the Worlds most amazing obstacle course?

Any obstacle course that doesn't include a moat with crocadiles, great white sharks and pythons will be severely lacking. That being said, in the army they make you crawl under machine gun fire, so that would be cool too.

Huge trees, crazy horses, diamond spike, lava, and maybe swords
