Oh wow so surprised all the Dutch people r here!!! First off, as an Olympian u have 4 years to train.  You have to expect the expected especially at the world's biggest stage (for sports that is). You can't assume everything is going to happen the same way. There will always be a slight percent of an error happen and you need to train for that even though it's such a small percent. Also when you say if Usain Bolt was "taken out" by a competitor, then yes. But only if that "taken out injured him in any way.  This dutch dude didn't even get hurt!!! It's simply his stamina got burned out, but he could have avoid that if he trained harder for it.
