Thrive San Diego Half Marathon & 5K

Thrive San Diego Half Marathon & 5K is held in San Diego, California, on November 14, 2026, with the half marathon (13.1 miles) starting at 7:15 a.m. and the 5K at 7:25 a.m. Both races start and finish at Ski Beach in Mission Bay. Entrants receive official gear, a medal and access to the Thrive Expo, and a virtual option is available for anyone who cannot be there in person.

Framed around staying active, eating well, living well and giving back, the event supports Make-A-Wish San Diego, with proceeds going toward granting wishes for children with critical illnesses. On the running side, the early start and the road setting favor an even, controlled effort: build toward a long run of about 10 miles if the half is your target, and use the 5K as a quick opener if you would rather race short.
