Green Valley Lake 5k/10k/& Half Marathon

Big Bear is the most legendary mountain resort in Southern California, and has long been a favorite training ground for some of the country’s top runners.

You’ll be following in their footsteps as you explore the picturesque trails of this venue, featuring buttery singletrack winding through high altitude pine forest, plus some gnarly, technical climbs and descents. You’ll experience wide views of the Southern Sierra, wildlife, wildflowers, and did we mention the altitude?

This weekend also features Spartan Obstacle Course Races.

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.
