Dirt in the air. Tires screaming through stone. Sun breaking over the Estrella Mountains of Goodyear, Arizona. The Estrella Cup is more than a mountain bike race — it’s a desert test of will, speed, and soul. Every December, riders of all ages line up on a hand built trail system, carving through fast singletrack, brutal climbs, and endless desert horizons. From youth riders and first timers to elite endurance athletes tackling a 10, 20 and 47 mile challenges, this is where limits are tested and stories are forged. Come for the battle. Stay for the tribe. This is the Estrella Cup.
