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.

my own experiences at herne hill are much like the poles
looking good, looking good, looking good
darn boxed in
OUT
it was fun for that first lap though ! had plenty of time to drink tea in the stands afterwards, which made up for my early exit
