• If you're talking about the hill the guy says it's supposed to be training for the final sprint in keirin races - as in putting out the power and dealing with the pain I guess, it's not a very informative program - he also says they've been doing it since the keirin school was founded which is probably the main reason they do it (tradition). Also it's probably supposed to be fun/relief from the usual repetitive training, a lot of the students seem to like it and they have races every year.

    Anyway I'm not sure how scientific the training methods are at the keirin school, they mostly just... ride a lot in the actual classes, although they have time to fit in their personal programs as well. I think much of it is about learning tactics and manners and whatever in races, and preventing any problems with the gambling by drilling them very strictly so they won't misbehave when they turn pro and weeding out anyone who can't take the strict lifestyle while races are being held.
