We will accept applications on Ultrasignup beginning 1/1/2019 through the deadline of midnight of 1/4/2019. A lottery will take place if over 300 qualified applications are received. If there are less than 300 applicants, entries will reopen on Ultrasignup on 1/5/2019 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, 2019. 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 the year prior to the start of the 2019 race as a requisite to participate or donate $100 to the SURF Mount Laguna sign project in lieu of their volunteer hours. We encourage entrants to volunteer through trail work on your local trails or the trails in the Mount Laguna District of the Cleveland National Forest where the San Diego 100 is largely run, but volunteering at an ultra or other race is acceptable. Please see our volunteer page for further information.
