A very good article by the BBC on the possibility of a sub-2:00 hr marathon. I doubt that I'll live long enough to see it, but some of you here should.

Coincidentally, today's Boston marathon was won in a new world record time, 2:03.2, by Geoff Mutai (Kenya). That time totally shattered Gebrselassi's 2008 record of 2:03.59 in the Berlin. But today's time isn't recognized as a world record because of a strong tail wind. Still, it was cool to see.
When JenPharr sets the new AT record, we'll have to check weather maps to see if she had an unfair tail wind advantage.
