At our indoor conference race this year, a teammate of mine was leading the 3k, with about 1k left to go. He and one other runner (the favorite and eventual winner, had put some distance on the rest of the field. Both looked really strong, and seemed guaranteed to go 1-2 (or at least finish in the top 3-4). Suddenly, on the far side of the track, my teammate just disappears. Since my view was blocked from the far side of the track, I initially thought he had faded drastically, but realized he was way to far back, even for this. After the race, I found out that a rival team's coach had stepped out onto the track right in front of him and basically just leveled my team's runner (throw's coach. He didn't tackle him, he was just a big guy). So my teammate went from running first to finishing out of scoring position. He was a little shaken up by the fall, but not too bad. The guy who won kind of slowed down to wait and see if our runner would get back up quickly, but once he saw the rest of the field closing he kind of had to take off. No repercussions for the other coach. He just stole 8-10 points and walked off. I think I was more mad than the guy who got tripped.
