He claims to have run a sub 5 mile last year during practice, but there is no video of him doing it. He refuses to try again since he puked all over and had headaches afterwards, so he has no desire to go through that again (even when I offered him a few hundred bucks if he succeeded at his current weight). He says he sprints and does intervals on a regular basis but does not do continuous distance runs.
He did show me a video of him running a hand timed 56.5 400 and a 2:13 800. So how plausible is his sub 5 claim given those PRs? Did he even break 5:10?
