San Diego, California (United States of America) - "La Jolla Half Marathon, 10K, & 5K". The La Jolla Half Marathon is one of America's most picturesque and beautiful point-to-point races. Starting at the Del Mar Fairgrounds, the course follows a scenic coastal route before reaching the challenging climb to the summit of Torrey Pines State Park. The course then rolls atop Torrey Pines mesa, continues down through residential La Jolla Shores, and finishes at La Jolla Cove. We also offer a 10K for anyone looking to skip the hill. Starting at the top of the mesa, our San Diego 10K follows a fast, coastal route that bypasses the Torrey Pines climb. For those interested in a shorter option, the La Jolla Shores 5K offers a mostly downhill course and features some of the most scenic views of the last 3.1 miles of the half marathon course. https://runsignup.com/Race/CA/SanDiego/LaJollaHalfMarathon5K?aflt_token=Nktw0AUB3nF4FPeh7Y7AWqQewFdw9sGt
