After 76 (yes, 76) days of effort Skyler Weeks has done what he feels to be the hardest jug-to-jug dyno in the world, Zion. It measures about 8 1/2 feet (~260cm) from start hold to finish, and jumps directly out a river-sculpted scoop in Clear Creek Canyon, Colorado. Skyler didn´t propose a grade for the climb. Skyler currently lives only for dyno climbing and holds the official dyno world record at 2.625 cm. He trains with Denver Nuggets, the professional basketball team. This footage as well as other huge dynos, will be included in Chuck Fryberger´s new film Pure, released in early 2009. Grade 8C+ speculation in comment 🙂
