Zavarzina started &lt;a href="2010%E2%80%9311%20FIS%20Snowboard%20World%20Cup"&gt;2010/11 season&lt;/a&gt; in very good form with two podiums from her first two races. By doing so, she reached a podium in a parallel slalom race for the first time in her career and became the part of the Russian podium sweep in Limone Piemonte, the first ever in the history of the Parallel World Cup. At the 2011 World Championships in La Molina, Zavarzina won the gold medal in the parallel giant slalom and became the second ever Russian snowboarder to claim a World title after Yekaterina Tudegesheva who won the gold medal, also in parallel giant slalom, in 2007. In the parallel slalom event, Zavarzina tore ligaments in her right knee and sustained a season-ending injury during the qualification round after setting the fastest time in the first run of the qualification in blue course. After her success in World Championships, Zavarzina was awarded the title of Honoured Master of Sports of Russia.
