I was completely exhausted after each of my lifetime PRs, from 400m up to the half marathon. Couldn't talk for several minutes, and either laid in the grass immediately after or slumped on the fence. There wasn't any warmdown after those efforts; I couldn't run another step. Just a slow hobble to the parking lot in each case, after which I was completely done for the day.
This woman looked like she could have kept banging out 33 second laps, for a final 5000 meter time under 14 minutes. So no, I do not buy at all, for one second, that this woman is clean.
Maybe she is just in much better shape than you ever were. Ever consider that?
