The SoCal 3×5 is a fun opportunity to recognize our dedicated 5K participants who complete a quality trio of 5K events. The series starts in January with the Carlsbad Surf Sun Run 5K featuring an out and back course that passes by the beautiful Buena Vista Lagoon and starts and finishes at The Shoppes at Carlsbad, the same location as the Carlsbad full and half marathon. Next is the La Jolla Shores 5K in April featuring a point-to-point course that starts at the top of La Jolla Shores Drive (near UCSD) and takes runners down to an exciting finishing at the La Jolla Cove sweeping ocean views all along the way. The series finishes in August with the America’s Finest City 5K, featuring a mostly flat loop course in historic and beautiful Balboa Park.

All three events feature fun, post-race festivals each complete with a craft beer garden, live entertainment and vendor booths.

The SoCal 3×5 is made up of the Carlsbad Marathon Surf Sun Run 5K in January, the La Jolla Shores 5K in April and the America’s Finest City 5K in August.
