GoPro Dual Slalom at the GoPro Mountain Games
2026-06-05 - 2026-06-07 | Vail, CO, Vail, United States
Head-to-head racing doesn’t get more intense than GoPro Dual Slalom at the Minturn Bike Park in Colorado. Riders drop in side-by-side on mirrored courses stacked with tight berms, massive rollers, and airtime-ready jumps — sprinting elbow-to-elbow all the way to the finish. It’s explosive, blink-and-you’ll-miss-it action where every pedal stroke counts and the crowd feels every turn.
