Overview: The San Diego 100 Mile Endurance Run takes place annually in the east county mountains of San Diego. This is the 19th Annual Event. The race start/finish venue is located at Lake Cuyamaca near the mountain community of Julian. This is about 50 miles east of San Diego.
Our event starts on Friday, June 2, 2023 at 6:00am and ends on Saturday, June 3 at 2:00pm. There is a 32-hour time limit with intermediate aid station cut-off times. The race has 16 well-stocked aid stations, with drop bags available at 8 of the aid stations.
The course covers 5 distinct areas including Lake Cuyamaca, Rancho Cuyamaca/Anza Borrego State Parks, Noble Canyon, Mt Laguna Recreational Area, and the Pacific Crest Trail (PCT). The course is 85% single-track technical trails and includes just over 13,000 feet of climbing/descent each. Course maps, routes, and turn-by-turn directions are located on the website Participant’s Guide.
Registration: The event has a 300-runner limit with qualification standards required to apply for entry. A lottery is usually required to select the starting field due to higher demand than our permits allow. A waitlist is maintained once the 300-entrant limit is reached.
Registration information to include qualification standards is contained in the Participant’s Guide. Registration opens at ultrasignup.com on January 1, 2023. Applicants will have 4 days to apply and will be notified if selected. Credit cards will not be charged until a runner is selected. Refund policies are delineated in the Participant’s Guide.
Lodging: The first weekend in June is an extremely popular time in the Lake Cuyamaca area. All entrants and supporters are highly encouraged to make reservations early. Options include camping, RV hookups, and a few cabins at Lake Cuyamaca, the Lake Cuyamaca Lodge, lodging in Julian, and the Mt Laguna Lodge. There are also camping options at Paso Picacho and Green Valley State Parks. Alpine and Pine Valley also have a motel option. More detailed lodging information is also located within the Participant’s Guide.
Crews, Driving Directions, and Solo Division: Supported runners are strictly limited to one crew vehicle. Crew Directions and allowable crew access points are contained in the Participant’s Guide. The race also has a Solo Division in which runners rely solely on aid stations and their drop bags. All Solo finishers receive special recognition. Supported runners are also allowed to have a pacer for the second half of the race. Pacer and Solo rules are also in the Participant’s Guide.
