Challenge Aspen athlete Danielle Coulter and guide Zander Higbie race on the giant slalom course at Snowmass during NASTAR national championships on April 6, 2021. Kaya Williams/The Aspen Times After taking a run Tuesday on the giant slalom course at Snowmass, Challenge Aspen athlete and alpine racer Chris Guay made a keen observation: “It’s not too often that you have professionals cheering you on.” But that’s exactly the case at this week’s National Standard Racing (NASTAR) national championships, 41-year-old Guay said. Along with a sizeable crew of Challenge Aspen staffers ringing cowbells at the finish line, Guay said he also felt support from U.S. Ski Team members Laurenne Ross and Paula Moltzan, who were on the course as pacesetters Tuesday morning.
