The Experience
The Fontana Days Run Half Marathon began back in 1955 with a reported 200 participants. Race founders were unaware that the annual Half Marathon would grow to include over 2,000 participants. 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 Family Fitness Walk, and a Children's Half Mile Dash. Finish Line festivities include local vendors, exhibitors, entertainment, and food.
