Coming back from double knee-surgery and two years off of skating, Klassen's main goal at the 2010 Winter Olympics in Vancouver was simply to compete. Klassen saying that "My goal is just to qualify. To get there would be great." She failed to medal in 2010, placing 21st in the 1500 m, 14th in the 3000 m, and 12th in the 5000 m. Klassen was also named as an alternate in the team pursuit. While Klassen stated that she was unsure of whether she would continue speed skating after the games, she believed that her knees would hold out and that the 2014 Sochi Olympics were a possibility.
