Once you see one BASE jump, sometimes it feels like you've seen them all. You'll probably reconsider as you watch this daredevil from Negative4 Productions gingerly tiptoe along the edge of this enormous, inactive wind turbine blade. Just as the blade starts moving beneath his feet... he's off!
Another elite sport that'll never disappoint is speedriding. Watch Vincent Pierré of SWITCH Snowboard School in France skim, soar and loop through the crisp winter air as he combines everything we love about skiing and paragliding.
