When Robert Kiprono Cheruiyot won the Boston Marathon Monday, he broke the course record time - but he didn't break the rules.
That's the ruling made by race organizers after WBZ-TV video footage (below) showed the Kenyan running out of the pack and onto a sidewalk before coming back onto the street in front.
Organizers say there are no sidelines in road racing, and as long as he wasn't cutting any corners, he didn't do anything wrong. They say they've watched the video and don't think Cheruiyot gained any special advantage from the move.
What do you think?
