This one was interesting to watch. 120 guys released into a very short course. At the first lap, the head of the group was at the start finish line while the tail was still entering the 180. After seven minutes, all but 20 guys had been whistled off the course. It was captivating to watch in a "watching a train wreck" sort of fashion. I felt bad for the 100 guys that payed for less than ten minutes of racing.
