Welcome to the first annual Mammoth 300 Ultra Bicycle Race 2015, presented by NdZone. The race starts at the La Quinta Inn, Bishop, CA, in conjunction with the White Mountain Double, on September 12th – 13th.

The start/finish and Rider Check-In will be at the La Quinta Inn (if you are not staying at La Quinta special rates are available until Sept 8.  See Lodging tab under the WMD pull down)

This is a unique event where a 300-mile bicycle race will be held together with a California Triple Crown Double. The 300-mile racers will start in a time trial fashion in front of the WMD riders.

The Mammoth 300 is the most epic challenge. The course is a loop around the White Mountain range with challenging route up to Mammoth and back to Bishop.

The racers enjoy the support and company of the White Mountain Double Century for the first two hundred miles, and up Sherwin Grade, towards Lake Crowley, self-support check- point at Mammoth Lakes, then go around Mammoth Scenic Loop, and back to Bishop racers finish
