It’s a story of the world’s top adventure athletes battling it out across the mountains and skies of the Alps in a bid to be crowned champion of the most important and challenging race on the calendar – the Red Bull X-Alps. That story is told in the official Red Bull X-Alps documentary: The Champions Challenge, which has just been released.

It not only tells the story of the battle at the front, following Chrigel Maurer as he hikes and flies around the 1,223km course followed by his challengers. But it also focuses on the 20-year anniversary and shows footage from the early years of the race. Click below to watch the full documentary and follow the athletes across the Alps!
