Course Description

The course is designed to highlight the very best of the Phil's World trail system. Riders will navigate a loop that balances heart-pumping climbs with exhilarating, gravity-defying descents. The trail surface is primarily high-desert singletrack, winding through piñon and juniper forests. Technical features include short, punchy climbs, tight switchbacks, and the occasional rock garden that demands precision. The elevation profile is rolling, meaning there are no mountain-sized climbs, but the constant "up and down" nature of the terrain will test your power output over the long haul.
