I am pretty sure it was the 200m he ran and he ran 20.6 or something. 200m on raw talent is a little more believable than an elite 400m.
That guy's a freak though. An outlier. I actually use that example to show just how freakish he is. It wasn't like he wasn't training though. He was training 5-6 days a week during football season and then took off 10 days of organized practice.
