Professional skier Markus Eder had a fantasy of an impossible descent that would take him across glaciers, through frozen tunnels, into a terrain park, even out of the back of a pickup truck. It made no sense. And yet somehow, over eight years, he found a way to make it happen by thinking more like an artist than an athlete. The result is [The Ultimate Run](http:// https://www.youtube.com/watch?v=fbqHK8i-HdA), a wildly creative stoke film that’s loaded with gnarly stunts and stands out thanks to the pure, contagious joy emanating from every frame. Somehow, we get to be inside Eder’s fantasy right along with him—which, as he tells it, is exactly what he intended.
