On the western slope of Colorado, the famous Kokopelli Trail winds its way through sagebrush, ledgy slickrock, winding double track, sandy washes, fast jeep trails and crosses the state line toward Moab, Utah. This trail is the site of the Desert RATS MTB Classic. The 50K & 100K endurance mountain bike races are challenging tests of stamina. Held in May, it’s a great early season test of fitness and a great reason to keep training through the winter and early spring. The courses cover a wide variety of terrain including challenging technical terrain, grueling climbs, fast flats and tricky descents.
