The Half Marathon Triple CrownSM is a fun opportunity to recognize the dedicated half marathoners who enter these three top quality events. With the three races spaced evenly apart in the winter, spring and summer, it allows participants plenty of time to train and recover from all three events.

All the half marathons are known for their spectacular scenery. The Carlsbad Half Marathon in January boasts an oceanfront course in Carlsbad, 30 miles north of San Diego. The La Jolla Half Marathon held in April features a point-to-point course stretching from the quaint seaside village of Del Mar to La Jolla with plenty of ocean views along the way. The America’s Finest City Half Marathon held each August, runs from the historic Cabrillo National Monument in Point Loma, along the San Diego Harbor and winds through downtown San Diego before finishing in beautiful Balboa Park.
