Who are we?

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 Race Walk, 5K Family Fitness Walk, and a Children's Half Mile Dash. Finish Line festivities include local vendors, exhibitors, entertainment, and food.

Fontana's Half Marathon Run is known as the fastest Half Marathon due to the gradual downward slope of the course as well as one of the oldest Half Marathons in the United States. There is an elevated drop of 2,125 feet from start to finish and because of this, most participants are able to record their personal record time (PR) in Fontana. Please note: Participants must maintain a 13-minute mile and/or pass the 15 freeway by 9:15 a.m. and the finish line by 11 a.m.
