Ok, so you might think the 100 meters, all natural talent, short race etc...
But the start takes a lot of training etc.
Maybe not at the Wariner/Merritt level... But to get to the 46-47 level.
Laziest guy on my college team could crawl out of bed, hung over, and throw down a victory in the 400.
What do you think is the easiest event to train for?
