I only ran a half Marathon once but i didn't train went out drinking the day before and am a smoker. I only ran because a friend got sick and asked me to run in her stead. I planned to stop after 5 or 10k but there was this guy with this timeflag in front if me so i just followed.

Long Story short: when my body started to tell me that He really wasn't in the mood anymore i was a Kilometer away from the finish line, so i finished...and spend the next month cursing my decision because everything hurt.

Anyway, i got offtrack because i misunderstood your debate: those time people are people which comfortably can run these times. So for sure a 3hr timesetter can run far below 3hrs
