From the rules :

It’s desirable that riders competing in this series are not focused on one particular facet or event of
track cycling.  We suggest riders mix it up and compete in both sprint and endurance events at this
level.

There's one pure sprint event on the program, a keirin, that according to the rules, you get graded on by your performance in .. enduro races!

Keirin Series:
Event-13 Women Under-15 (6 Laps) Heats based on points totals from earlier events
Event-14 Men Under-15 (6 Laps) Heats based on points totals from earlier events
Event-15 Women Under-17 (6 Laps) Heats based on points totals from earlier events
Event-16 Men Under-17 (6 laps) Heats based on points totals from earlier events

Full rules here.

I'm not going to say anything more about this.
