Course Records
The table below shows you the names of the skiers who hold the course records for each race, and their times. Each year, we hope for a field of competitors who will challenge and, perhaps even best, the recordholders! But for now, these exceptional athletes hold the title of "best of the best" in America's Toughest Ski Race.
