Three of the country's best half marathons.

Three exceptional coastal courses.

Three "must-do" races.

One unique challenge.

To be a part of the series, simply register and finish each of these events in the same calendar year, starting with the Carlsbad Half Marathon (or marathon) in January. Finishers of the Half Marathon Triple Crown will receive an impressive commemorative medal and will be recognized on Triple Crown web site as finishers of the "Half Marathon Triple Crown."

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

All of 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. The America's Finest City Half Marathon (AFC), held each August, runs from the historic Cabrillo National Monument in Point Loma, then along the San Diego Harbor before winding through downtown San Diego and finishing in beautiful Balboa Park.
