San Diego’s premier fall running event returns for its 5th year on Saturday, November 6, 2021. The perfect tune up race for fall marathon training, the new half-marathon loop course will start and finish along the waterfront in Mission Bay and features 13.1 miles of fast and flat stretches, bay views and ocean breezes. The 5K scenic loop course also starts and finishes at Ski Beach. Wrap up the day with the Thrive Expo to get connected with local health and wellness vendors.
