San Francisco 50mi/50K Endurance Run

Enjoy vistas of the Pacific Coast as you take a scenic tour of the spectacular Marin Headlands with views of Tiburon, Pirates Cove, San Francisco and the Golden Gate Bridge. The course is a 25-mile washing machine loop. The first loop is clockwise. Then, 50 milers do a counterclockwise loop. And the 50K runners do the 6-mile Wolf Ridge loop to finish up.(Distances are accurately measured using a Rolatape® surveyors measuring wheel.)
