The La Jolla Half Marathon is one of San Diego Californias most picturesque and beautiful point-to-point races. Starting at the Del Mar Fairgrounds, the course follows a scenic coastal route along the San Diego coast and reaches the challenging climb to the summit of Torrey Pines State Park. The race course then rolls atop Torrey Pines mesa, continues down through residential La Jolla Shores, and finishes at La Jolla Cove. And, for those interested in a shorter option, the 5K race course offers a mostly downhill course and features some of the most scenic views of the last 3.1 miles of the La Jolla half marathon course.
