Lace up your trail shoes for the Coyote Hills Half Marathon, 10K, and 5K, set to take place on January 31, 2026, in scenic Fremont, CA. This popular event, organized by the experienced Brazen Racing, promises a refreshing start to the year with courses that beautifully showcase the natural splendor of Coyote Hills Regional Park. Runners will traverse a diverse landscape, enjoying breathtaking views of the San Francisco Bay, expansive marshes, and rolling hills on a mix of dirt trails, paved paths, and unique wooden boardwalks.

Despite the "Hills" in its name, the Half Marathon course has been updated to significantly reduce elevation gain to 678 feet, making it an accessible trail experience for many, though still featuring some memorable climbs. The 10K offers 184 feet of gain, and the 5K a gentle 107 feet. Participants consistently praise the race for its well-marked courses and the enthusiastic support from volunteers. Typical race day conditions in late January include comfortable highs around 60F and lows around 44F, with a low chance of precipitation, creating ideal running weather.

Whether you're tackling the full 13.1 miles, the 10K, or the 5K, you'll find a well-supported event. Aid stations, fully stocked with water, sports drinks, gels, pretzels, and candy, are strategically placed along the routes: one for the 5K, two for the 10K, and three for the half marathon. For those who prefer a more leisurely pace or expect to take longer than 3.5 hours for the half marathon, a "Hiker Division" is available with an earlier start. The race begins and ends at the Dumbarton Quarry Campground, providing a convenient and welcoming hub for all participants.
