Black Diamond is a title sponsor of the 2019 Cirque Series. The three-year-old series is holding six mountain-running races at ski lodges in North America. This year's locations are Brighton, Alta, and Snowbird in Utah, Alyeska in Alaska, Arapahoe Basin in Colorado, and Sun Valley in Idaho. Runners may compete in three categories: pro, expert and sport, in decreasing order of intensity. They begin at the lodge, make their way up past ridges and glacial cirques into the alpine zone, and then work their way back down to the ski village, where they're welcomed with live music, food, drink and vendor tents. Pro winners receive cash prizes. Expert and sport winners receive gear.
