About the Thrive San Diego Half Marathon

The Thrive San Diego Half Marathon & 5K is held on a Saturday in early to mid November on Mission Bay in San Diego, California. The half marathon is a 13.1-mile loop around Mission Bay that starts on Ingraham Street and finishes at Ski Beach on Vacation Isle, on a mostly flat course with bay views. A half marathon relay splits the loop between two runners with a handoff at Tecolote Shores, and the 5K is a loop along Crown Point with the same start and finish. The race benefits Make-A-Wish San Diego and is produced by Easy Day Sports.
