The 2021 series will kick off with Carlsbad on January 17, followed by San Diego on March 21, and conclude with America’s Finest City on August 15.

Now more than ever, we all need something to look forward to and a reason to keep putting in the miles! Why not commit to the 2021 Half Marathon Triple Crown or SoCal 3×5 series and register for race one – Carlsbad – today?! We’re hoping to hold an in-person event in January, but because the future is a bit unknown right now due to COVID-19, here’s our peace of mind registration policy.

For those working on your TRIPLE Triple Crown or SoCal 9×5, the addition of the San Diego Half and 5K doesn’t change your eligibility – learn more here.
