The 2013 U.S. Cross Country Ski Championship continued on the trails of Soldier Hollow in Midway, Utah with the senior women's 20 k classic mass start. The lead pack was established early with just six women in contention for the national title throughout the majority of the race. On the course's final major climb, Hermode's Hill, it was Sadie Bjornsen (USST/APU) who attacked, opening up a sizable gap by the time she entered the stadium. Check out our footage of the action.
