Chicago Marathon Winner Even Slips Quickly

What's more painful than running a marathon? How about slamming your head on the pavement at the very second you finish? Robert Cheruiyot won the Chicago Marathon with a time of 2:07:35, but slipped at the finish line and suffered a concussion. Decals on mat: You have been Deactivated. Glad he's OK, though he has been advised to take a break from running.
