A big thank you for all participants for running the San Diego 100. We will see you at the 2019 race.
We'll accept applications on Ultrasignup beginning 1/1/2018 through the deadline of midnight of 1/4/2018. A lottery will take place if over 300 qualified applications are received. If there are less than 300 applicants, entries will reopen on ultrasignup until the 300 person limit is reached. A waitlist will be maintained on Ultrasignup once the field limit of 300 is reached. The latest date for wait listed applicants to receive a slot is April 15, 2018. After that date, there will be no refunds for entrants and no other applicants will be accepted.
All entrants are required to perform 6 hours of volunteer work within a year prior to the start of the 2018 race as a requisite to participate. We expect entrants to attempt to accomplish their volunteer work on trail maintenance but volunteering at an ultra or other race, or by volunteering at a community service is acceptable.
The start and finish line are at Lake Cuyamaca which is located at 15207 Highway 79 near Julian, CA. The Lake Cuyamaca web site (with information about camping and RV reservations) is located at: Lake Cuyamaca Website. Also check out additional lodging options under this web site's Event Info link to Accommodations.
