At 10 p.m., Saturday, Jan. 26th, H.T. Welling, president of the Oakland Club, was given the word to go, at the Service Garage, San Leandro, and the first half of the big contest was on. The first section of endurancing called for 372 miles of riding in 18 hours on a 20-mile schedule per hour. The course was a 63-mile circuit, from San Leandro to Alvarado, to Warm Springs, to Pleasanton, to Dublin, to Castro Valley and return, the route to be covered six times. All kinds of riding surface was embraced from gravel beds to chuck holes, and miles of dusty roads.
