For the guys in the Vibram/Barefoot Running discussion several posts back:

An 11 year old kid ran the half-marathon in Myrtle Beach, barefoot, with a time of 1:38:54 on Saturday. The roads here have broken glass, construction debris, pebbles, etc. He said he didn't have a problem.
Also if there is a recruiter here, the winner of the 5K on Friday was a 16 year old kid with a time of 16:46. Sign that kid up in a year or two. BN
