Olympics 2012 track cycling

It's not logical, it requires repeated sprint and recovery. The riders at the back aren't really slower, the whole group is moving at exactly the same average speed, they are however protected from drag by the rides in the front. The Polish girl tried to sprint from the back every elimination lap from the start and was looking good until one lap she found herself boxed in....and was out.

Trott uses positioning and the ability to get through gaps as much as repeated kicks though. She does well in the devil because of her mad bike handling skills.
