Pacifica Foothills Trail Run

The Pacifica Foothills Trail Run takes place on January 23, 2027, in Pacifica, California, and offers three trail distances: a 30K (18.6 miles), a half marathon (13.1 miles) and a 10K. All three run in the foothills above town, and the same route family serves each option, so the difference between them is duration rather than character.

Coastal California trails in January mean soft, giving ground, and that changes how you should approach the day. Expect climbing, walk the steepest pitches without treating it as a failure, and let your effort rather than your splits set the pace. A runner with a regular weekend long run can step up to the half marathon here; the 30K asks for two or three months of hill work and a long run that has already passed the two-hour mark. The 10K makes a manageable introduction to trail racing.
