The First ‘Across the Bay’ Race: A Celebration of Running


As the 37th running of the Across the Bay 12K goes virtual for the first time in its history, Run Local got together with the race’s founder, Dave Rhody, for a behind the scenes look at how it all came together. Listen to our Run Local Pod and enjoy his written words and photos.

The Across the Bay 12K is a Pacific Association USATF Grand Prix Event.
