On August 21st at Mammoth Mountain, Cam Zink will look to make history as he attempts to land a Guinness World Record for the longest dirt-to-dirt mountain bike backflip. He has his sights set at the 100-foot mark, which would shatter the previous 78-foot record. From this practice video and photos he’s well on his way to making it happen!
