Despite the pain and fatigue from injuries, a further competitive gear was found for Klassen as part of the women's team pursuit. She became a part of the team that first won gold at the 2011 World Championships and then came back at the 2012 Worlds to win a silver as repeat medallists. That same season she had also helped to pull the women to the top of the World Cup title, winning three of four races that year together with Brittany Schussler and Christine Nesbitt.
