Keirin
Definition
Riders compete in a sprint after completing a number of laps behind a motorized pacer who leaves the track 600/700 meters before the finish.

The pacer shall ride within the sprinter line, starting at 30 kph and shall gradually increase speed to 50 kph which should be achieved at least 4 laps to go (250 m tracks). He shall leave the track as directed by the Commissaires, in principle 600-700 metres before the finish.
For Junior Women and Elite Women the respective speed shall be 25 kph and 45 kph.

Total distance is 2km so 4 laps at HH would be sensible enough
