I was just thinking the other day that someone could pick 26 people from work - the 26 fastest even - and allow them to each run a mile in a giant relay; and I would still beat them. In fact, I would probably beat them handily. I don't know that you could come up with 26 people in my site of roughly 3,000-4,000 employees who could run under 6:00 for the mile.
And it would probably be tougher, but now I'm thinking I might be able to beat 52 other guys each running a 1/2 mile leg.
I know this means nothing in the real world, but it would be a fun thing to try and put together.
