For most of us, mountain biking is a great way to get into the outdoors, get a workout, get an adrenaline rush, and hopefully avoid losing any skin or breaking a collarbone. For the mountain bikers of Red Bull’s annual Rampage contest, mountain biking is a means of defining the limits of human performance and fear tolerance. Every year, these men and women gather on a sprawling ridgeline near Zion National Park in Utah, and proceed to see who can ride the least rideable-looking line down a mountain bigger than your last 5 descents, combined. It is one of the most unbelievable spectacles in the world of action and outdoor sports, and since it’s about to go down this weekend, we asked our friends at the Pinkbike Podcast—who know more about mountain biking than just about anyone on Earth—to give us a little preview of the what, who, and why to watch.
