Run Against Breast Cancer 5k 10k & 13.1- San Diego, CA

Embrace the beauty of San Diego’s coastline on December 2 while standing united against cancer. The event offers three race choices – a spirited 5K, a challenging 10K, or a testing 21K Half Marathon. But it’s not just a race; it’s a collective stride against cancer. A portion of the run proceeds, combined with 100% of the fundraising, directly benefits the American Cancer Society, a cornerstone in the fight against cancer in the United States.

With high demand, waves for this run quickly reach capacity, with wave registrations closing as soon as they’re full. But don’t worry, there’s a virtual run option and a waitlist for those who miss their chance. The event is designed for intimacy, capping participation at just 15 participants per wave. All ages and paces are encouraged to join this run, including those under 18 with a guardian. There’s no need for elaborate equipment or complicated setups; it’s all about the purity of running. Timing is stress-free, with no timing chips required, though optional bib numbers are available for those who wish to track their performance. The swag bag includes a premium running shirt and a finisher’s medal, symbols of your commitment to this noble cause.
