Series of 4 titles
Extreme sports have always taken the trail less shredded. See rock climbers, mountain bikers, kayakers, and other inventive athletes return to their roots to practice their crafts in nature. They'll accept any challenge nature presents, resulting in some of the most gasp-worthy stunts ever seen. See the first person to climb Yosemite's El Capitan with no ropes. Watch high-liners walk a tightrope between cliff edges. Fight nature-deficit disorder and discover your own "adrenaline zen."
