The SoCal 3×5 is a fun opportunity to recognize our dedicated 5K participants who complete this quality trio of 5K events. Finishers of the SoCal 3×5 will receive a beautiful commemorative medal and some serious 5K bragging rights at the end of the series!

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), takes runners down to an exciting finishing at the La Jolla Cove and has 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. SoCal 3×5 finishers will claim their additional series medal at the AFC Finish Line Festival.



Once you complete the Carlsbad Marathon Surf Sun Run 5K and the La Jolla Half Shores 5K, you’ll be eligible for the SoCal 3×5! Check your eligibility here.

As soon as you confirm you’re on the list be sure you are registered for the America’s Finest City 5K. You will receive a special SoCal 3×5 bib for the final race, the America’s Finest City 5K in August. You will use this bib to redeem your commemorative SoCal 3×5 medal after your race.

If you think you should be on the list and don’t see your name, please email us with your name, bib number and finish times for Carlsbad and La Jolla.
