While gazing on the precariously curved 500-meter ice track—which begins at the Cathedral of Saint Paul before swiftly descending 12 stories to the finish line—it isn’t difficult to appreciate the steely nerves needed to compete in a downhill ice cross skating championship. The annual Crashed Ice competition will return to St. Paul for the seventh consecutive year, marking the inaugural stop in a globe-spanning itinerary that encompasses such cities as Jyväskylä-Laajis (Finland), Marseille (France), and Edmonton (Canada). Though the corkscrewing course conjures anxiety on its own, athletic aspirations raise the stakes even higher, as the reigning men’s champion (and first man to hold the title for two years running), Cameron Naaz, is a Lakeville native aiming for a historic triple victory. Not to be outdone, the women’s circuit offers the deft athleticism of Jacqueline Legere, a professional stunt woman who captured the championship in the 2015-16 season. Look for a complete schedule at www.redbullcrashedice.com. 5 to 10 p.m. Friday and Saturday.
