Estrella Cup MTB Race

Estrella Cup MTB Race is a mountain bike event in Goodyear, Arizona, on December 5, 2026. Two courses start at 7:00 AM: a 47-mile with about 3,700 feet of climbing, and a 20-mile with about 1,350 feet. The two options share the same Estrella desert terrain and the same morning, with the long course roughly doubling both the distance and the vertical gain.

Desert mountain biking in December is about tire choice and hydration more than about raw power: the ground is dry and loose, the sun is low, and the temperature swings between the start and the finish. The 20-mile suits a rider with a regular weekend habit, while the 47-mile is a half-day effort that deserves a proper feed plan and a spare tube. Either way, ride the terrain, not the numbers on your computer.
