A three day mountain biking race, we are proud to be the host along with other locations in the area, Glorieta and Galisteo Basin.

Stage 1 kicks off in the heart of Los Alamos, starting and finishing near the Manhattan Project National Historical Park Visitor Center.

A uniquely iconic setting where history and high-desert riding intersect. From the first pedal stroke, riders will feel the energy of this landscape: volcanic mesas, deep canyons, and forested ridgelines shaped by millennia.

Free and open to the public, Chillville at Ashley Pond Park will offer:

  • Food + beverage vendors
  • Local artisans
  • Expo area
  • Live Music
  • Family-friendly activities
