MAMMOTH - Reno mountain biker Cam Zink set a new world record on Thursday night.
Zink set the Guinness Book of World Records for the longest dirt-to-dirt backflip. He cleared 100 feet, three inches. It breaks his own unofficial record of 78 feet which he set earlier this summer.
Zink also set another world record during the practice session. That was the longest straight air dirt-to-dirt jump, clearing 119 feet, nine inches
The event was shown live on ESPN. It will air again this Sunday on the World of X Games. That begins at 11am on KOLO-TV.
