I guess the youngest guy who's run his age was Coghlan, who ran sub-4:00 when he was over 40. I wonder who the oldest guy is--maybe some centenarian who clocked a sub-10:00 mile?
I'm pretty sure there have been some 35 year olds who have run 3:50.[/quote]
Yeah, but a 35-year-old--divided by 10--would have to run 3.5 minutes for the mile. Nobody's done that yet...
