EVENT DESCRIPTION
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.
RACE HISTORY
The Fontana Days Run is an internationally renowned race recognized by the USATF as the World's Fastest Half Marathon Course since 1985. The Half Marathon (13.1 miles) starts in the San Bernardino National Forest at an elevation of 3,800 feet and drops nearly 2,125 feet to the finish line in front of Fontana City Hall. Due to the gradual downward slope of the course, many runners use the Fontana Days Run to improve their personal record or qualify for larger races. In addition to the Half Marathon, there is a 5K Run, 5K Family Fitness Walk and a Children's Half Mile Dash so the whole family can participate.
