Cemex Quarry Quest 5K Rialto

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.

This will be the 47th Run Through the Pines

Save the date and please follow us on our Run Through the Pines Facebook and Instagram page.

The Run Through the Pines is a destination run and a San Bernardino, Rim Mountain Community Event. It is one of the longest "running" runs in Southern California (the first one was in 1979). It features a 10K and 5K run (or walk) around Lake Gregory and through a pine tree forest. Runners (and walkers) can enjoy a semi-paved course at a 4,720-foot elevation, which makes it a perfect little challenge for mountain locals and especially our friends from down the hill. Race day staging is at the San Moritz Lodge “Meadow” area near the Lake Gregory Company bait and tackle shop. We encourage participants of all levels, children in strollers, pets on a leash, and especially teams/groups.

Lake Gregory is located in Crestline, a charming little town filled with one-of-a-kind shops and restaurants. We encourage all runners to stay the weekend and enjoy the town.
