Embark on a challenging yet breathtaking journey at the Pacifica Foothills Trail Run on January 24, 2026, in scenic Pacifica, CA. This highly-regarded event, organized by Inside Trail Racing, offers three demanding distances: a 30K with a formidable 4,300 feet of elevation gain, a Half Marathon climbing 3,100 feet, and a 10K with a respectable 1,200 feet of ascent. Held in the expansive San Pedro Valley Park, the courses wind through 1,150 acres of coastal mountain environment, featuring mostly moderately technical dirt trails, twisty single-track sections, and some fire roads. Runners consistently praise the race as "murderous but beautiful" for its relentless climbs, particularly the ascent up Montara Mountain, which rewards with panoramic views of the Pacific Ocean and the Farallon Islands. Typical race day conditions in late January include comfortable highs around 59F and lows of 45F, with a low 12% chance of precipitation, creating ideal trail running weather.

The Pacifica Foothills Trail Run is renowned for its stunning scenery and well-executed organization. As you navigate the eucalyptus groves and coastal foothills, keep an eye out for Red Tail Hawks, and if the winter rains have blessed the region, the spectacular three-tiered Brooks Falls dropping 175 feet. While the challenging terrain means aid stations are fewer and farther between, they are well-stocked with an optimal variety of glycogen-replenishing and electrolyte-replacing products, including gels, chews, Stroopwafels, pretzels, fruit, and Skratch Labs hydration mix. However, runners are strongly encouraged to carry at least one 20oz water bottle, as this is a cupless event designed to minimize environmental impact.

The race starts and finishes at the South Walnut Grove Picnic Area within San Pedro Valley Park, offering a family-friendly atmosphere with picnic areas and BBQ pits for spectators to enjoy while awaiting their runners. With a capacity of 350 runners across all distances, this event provides an intimate and focused trail running experience that promises both a physical test and unforgettable views. Prepare for a rewarding challenge that combines the beauty of the California coast with the thrill of significant elevation gains.
