San Diego 100 Mile Endurance Run

About an hour’s drive from San Diego, Lake Cuyamaca is a picture-book 110 acre lake that is proof positive that good things come in small packages. Situated at an elevation of 4600 feet in an Oak and Pine forest, it is surrounded on three sides by the 26,000 acre Cuyamaca Rancho State Park, which is 52% wilderness. Lake Cuyamaca is the perfect getaway for one day or up to ten nights. Few places in San Diego County offer the pristine views that greet your eyes wherever they may wander. 

Lake Cuyamaca is host to the The San Diego 100 ultramarathon. San Diego 100 starts and ends at Lake Cuyamaca, up in the mountains, with the majority of the race at 4-5,000 feet of elevation. The course covers four recreational areas in the east county mountains of San Diego: The Pacific Crest Trail (PCT), Noble Canyon, the Cuyamaca and the Anza Borrego State Parks, and Mt Laguna Recreational Areas.
