The Experience
Since 2010, the Summer Breeze half marathon has drawn nearly 340 finishers from a dozen states to Marina Park in San Leandro, with a repeat rate around 11%. The course is a pancake-flat out-and-back on the Bay Trail — roughly 50% paved and 50% packed dirt — making it a favorite for runners chasing a PR.
The route hugs the bay, offering coastal views that keep the miles interesting. Weather is a wildcard: early-August conditions average 56–69°F with 81% humidity, but fog can roll in. Aid stations appear every couple miles, laden with water, sports drink, GU, and unusual goodies like Oreos, Jelly Bellys, and potato chips.
Brazen Racing’s production is polished: free parking, same-day bib pickup, and free race photos posted quickly. The post-race food is a highlight — often featuring It’s-It ice cream sandwiches — and the finisher medal (or woodalion) caps a great morning. With a friendly, low-key vibe and a fast course, Summer Breeze is a hidden gem worth traveling for.
