Runners start the out-and-back course for the Summer Breeze Half Marathon in San Leandro’s Marina Park, and from there head along the Bay Trail through the Hayward Regional Shoreline, filled with more than 1,700 acres of marshes, wetlands and public trails. The mostly trail course never strays too far from the water and features a mixture of paved and gravel trails that wind their way through the Hayward Seashore’s salt and freshwater marshes.
