Rider Perks

Riders who want to be included in the King/Queen of the Mountain need to join the UCI Anti-Cancer Challenge STRAVA Group and then utilize STRAVA during the ride. The segment begins at the bottom of Pacific Island Drive (PID) and finishes at the peak. The KOM/QOM will be awarded to the fastest male and female participant on the PID climb segment.  The event staff will review the Anti-Chancer Challenge Group after the ride and look for the fastest PID Climb segments.   Only the 66 mile and the 100 mile routes are eligible for the KOM/QOM.
