Who it's for
This event is for experienced cyclists who enjoy significant alpine climbing and are looking for a unique format where they can choose their own order of timed ascents, prioritizing either performance or scenic enjoyment.

Training should prioritize long, steep interval climbing efforts, endurance for multi-hour efforts, and consistent elevation gain, alongside descending skills for the untimed downhill sections.
