Myhrer celebrated his first victory in the second World Cup slalom of the 2006/07 season in Beaver Creek. However, he had to wait over three years for his next podium finish. At the 2007 World Championships in Åre , the Swede only finished 20th in giant slalom and 22nd in slalom. In 2009 he stayed in Val-d'Isère after two failures with no result. At the 2010 Winter Olympics , Myhrer won the bronze medal in slalom. On January 6, 2011, he celebrated his second World Cup victory in the Zagreb slalom. At the 2011 World Championships in Garmisch-Partenkirchen , he was tenth in the slalom. In the 2011/12 season , Myhrer won the last two slalom races in Kranjska Gora and Schladming , plus four more podium places. At the World Cup final, he was able to intercept Ivica Kostelić and Marcel Hirscher in the Slalom World Cup , both of whom did not make it into the points. Myhrer became the third Swedish crystal ball winner after Ingemar Stenmark and Thomas Fogdö .
In the 2012/13 season , Myhrer could not quite maintain this level: With a win in Levi and two second places, he finished fourth in the discipline ranking. At the 2013 World Championships in Schladming, he just missed a medal in fourth place in the slalom. After Myhrer had lost touch with the world's elite a little in the following years, he increased his performance again in the 2015/16 season and achieved three podium places. In the last race of winter, the St. Moritz slalom , he celebrated his first World Cup victory in more than three years. He celebrated one more World Cup victory in the 2016/17 season and one in the 2017/18 season.
The then 35-year-old achieved the greatest success of his career at the 2018 Winter Olympics in Pyeongchang by winning the slalom gold medal, ahead of the Swiss Ramon Zenhäusern and the Austrian Michael Matt . He achieved two podium places in the 2018/19 season , but only finished 13th in the slalom of the 2019 World Cup in Åre. Myhrer considered ending his career at this point, but opted for another season as he felt comfortable in the newly introduced parallel races. His career finally ended at the end of the 2019/20 season ; as this had to be stopped prematurely due to the COVID-19 pandemic , he contested his last race on February 8th.
