Video: Rey Del Rio Waterfall World Championships - Kayaking Competition at its Most Extreme

Kayaking competitions are nothing new, nor is paddling over massive waterfalls. We've certainly seen both over the years. But when you combine the two, you get the Rey Del Rio Waterfall World Championships, an insane event in which pro kayakers run three massive falls in Chiapas, Mexico, pulling tricks and stunts as they go. The video below captures the insanity of this competition, where some big names in the world pro paddling gathered to take on the waters of the Agua Azul. As you'll see, it was quite the event.
