Good news for fat bikers in Round Valley. The seven-mile loop crews began grooming last winter, dubbed the “Fat Loop,” returns for the 2017–18 winter season, enhanced by a three-mile fat-friendly singletrack loop along the new Downward Dog and PorcUclimb Trails. And while all Round Valley trails are open to all users (with the exception of the Land of Oz Trail, reserved for cross-country skiers), Mountain Trails Field Manager Rick Fornier recommends these rules of thumb: walkers and snowshoers stay on the outside edge of the groomed surface (opposite the classic ski lanes), skate skiers get the middle, and if you’re a fat biker, please wait until the trail surface has set up so you don’t leave ruts. One more thing. “Please deposit dog waste bags in the cans placed along the trails,” Fornier says. “Sometimes we don’t see them on the edge of the trail, and they get caught in the tiller and shredded.” Nobody likes a poop loop.
