71st Annual Fontana Days Run

Prepare for an exhilarating journey at the 71st Annual Fontana Days Run on June 6, 2026, in Fontana, CA. This historic event, one of California's oldest road races, draws over 2,000 participants annually and is renowned as the "World's Fastest Half Marathon Course" by the USATF since 1985. Runners looking to achieve a personal record will thrive on the Half Marathon's unique downhill profile. Starting at an elevation of 3,800 feet in the scenic San Bernardino National Forest, the 13.1-mile course plunges over 2,100 feet to the finish line at Fontana City Hall. The initial six miles feature a steep descent through winding hills and the beautiful Lytle Creek Community, transitioning to a moderate, yet still fast, downhill grade along Sierra Avenue for the remaining 7.1 miles.

Beyond the iconic Half Marathon, the Fontana Days Run offers a variety of distances to engage the entire family, including a swift 5K Run, a 5K Family Fitness Walk, and a lively Children's Half Mile Dash, all culminating at Fontana City Hall. Participants in the Half Marathon and 5K events will be conveniently bused from City Hall to their respective starting lines. Runners consistently praise the excellent on-course support and the overall festive atmosphere of this well-organized event. Typical race day conditions in early June include comfortable lows around 59°F and highs around 84°F, with virtually no chance of precipitation, providing ideal weather for a fast race. All finishers across the Half Marathon, 5K, and Children's Dash will earn a well-deserved medal, with additional place medals and prize money for top performers. The celebration continues after the race with an expo at the finish line, featuring local vendors, exhibitors, entertainment, and food.
