Originating in 1955 with only 200 participants, the Fontana Days Run has grown to host over 2,000 participants and continues to be named one of the fastest half marathon courses in the world. With an elevation drop of over 2,100 feet from beginning to end, most participants are able to record their personal record time (PR). The Fontana Days Run provides participants with a safe, festive, and well organized event. The Annual Fontana Days Run features a Half Marathon, 5K Run, 5K Race Walk, 5K Family Fitness Walk, and a Children’s Half Mile Dash. Finish Line festivities include local vendors, exhibitors, entertainment, and food.
