The San Diego Half Marathon has been designed to carry runners over a spectacular 13.1-mile USATF-certified course, while showcasing one of the world's most beautiful cities! Our signature scenic route begins at Petco Park and winds through downtown to Harbor Drive with views of San Diego Bay, San Diego's skyline, Spanish Landing and Cancer Survivor Park. Then it makes its way through historic Liberty Station while passing NTC Park and the Marine Corps Recruit Depot. Next it's up Washington Street through Mission Hills and Hillcrest. The last few miles coast downhill, passing the scenic palm trees that line Balboa Park and lead right back into downtown, with an unforgettable 5th Avenue finish - featuring a live jumbotron and Gaslamp Block Party! USATF Certification Code: CA15087RS.
