Klassen became the first Canadian to win five medals in one Olympic Games. With this achievement, she tied American Eric Heiden's record of five medals won at an Olympics (1980) by a speed skater. At the same time, she overtook the previous Canadian record of most medals (three) in 1984, held by Gaétan Boucher. Klassen also became the first female speed skater to win five medals in a single Olympics, surpassing Lidiya Skoblikova's four medals in the 1964 Olympics. Combined with her bronze medal at the 2002 Winter Olympics, she became the first Canadian to win six career Olympic medals, surpassing the five medal mark set previously by Marc Gagnon and Phil Edwards and matched in the same race by winner Clara Hughes at the same 2006 Winter Olympic games.
