One of my runners that I coach took second and was disqualified after running a 4:08 1600. He passed on the inside and they disqualified him for impeding the other runner saying there was contact. When I watched the race video I didn't see any contact. Unfortunately because of this disqualification it cost us second place for our team and a school record. I realize these things happen. It just seems like a rule that is up to interpretation by the officials. I was just wondering how the impeding runner rule works?
