Match sprint rules/tips?
So, I'm thinking about racing friday and I've heard that not only will there be the regular c-d races, but also match sprints. While I understand the in's and outs of points races, miss-n-outs, etc I'm not 100% clear on the sprints. Specifically how one claims sprinters lane. For example, if the lead rider is riding above sprinters lane, say in the middle of the track, and the trailing rider is up top. The trailing rider decides to attack under the leader, and the leader also dives for sprinters lane what happens? I tried to look at a few videos and it looks like the trailing rider normally takes sprinters lane, but is this always the case?
are there specific rules for yielding the lane or is it simply first come first served, and the lead rider "tends" to be surprised by the move that they don't have time to make it to the lane?
This will be my first time racing, so I want to make sure I don't make any serious errors.
