Gretchen Bleiler is peaking at the right time. The 28-year-old snowboarder "went to a whole other level" at the Winter X Games last month to claim her record fourth superpipe title. "It feels amazing to win that. I finally stepped up to my potential," she tells TVGuide.com. "I know I'm capable of doing more at the Olympics." The Aspen, Colo., native, who nabbed silver in Torino, is back to win gold and is contemplating a never-before-landed trick in the women's competition to help her do it: the 1080 (three revolutions in the air).
