Fontana Days Run

Runners dash toward the finish line during the 5K Run in Fontana in 2018.  This year's Fontana Days Run will take place on June 1.

The 64th edition of the Fontana Days Run will take place on Saturday, June 1.

The Fontana Days Run is known as the world's fastest half marathon because of its gradual downhill course along Sierra Avenue from Lytle Creek to Fontana City Hall.

In addition to the half marathon, the event will also include a 5K Run, 5K Race Walk, 5K Family Fitness Walk, and a Children’s Half Mile Dash.

Finish line festivities include local vendors, entertainment, and food. Special awards will be given to the winners.

The northern part of Sierra (north of the finish line at City Hall) will be completely closed off to traffic throughout the morning of June 1.  Motorists are urged to take alternate routes.
