Piru 20K Time Trial - CA

Piru 20K Time Trial - CA is a cycling event held in Fillmore, California, on October 4, 2026, starting at 9:00 a.m. The single format is a 20K (about 12.4 miles) individual time trial, ridden against the clock rather than in a pack.

A 20K time trial is a pure test of sustained power: roughly 25 to 40 minutes of riding at or just above your threshold, with no drafting and no tactics to hide behind. It is a good fit for road cyclists who want a clean benchmark of their fitness, for triathletes polishing their aero position before a late-season race, and for newcomers curious about racing without the stress of a bunch start. Prepare with 8 to 10 weeks of structured work: two threshold sessions per week (for example 2 x 15 minutes or 3 x 10 minutes at time trial effort), plus longer aerobic rides. Rehearse your pacing so that you start controlled and finish empty, and test your equipment and clothing on the same kind of road before the event.
