Silver Strand, or simply The Strand, is a low, narrow, sandy isthmus or tombolo 7 miles (11 km) long in San Diego County, California partially within the Silver Strand State Beach. It connects Coronado Island with Imperial Beach. Together with the Point Loma peninsula it shelters and defines San Diego Bay. State Route 75 (SR 75) runs the length of the strand and is a popular site for jogging and bicycling. The Silver Strand Half Marathon is run along the route each November.
