Ager comes from Söll in Tyrol . She contested her first FIS races as a 15-year-old in December 2010. In August 2011 she was among the top ten for the first time at this level during the summer training in Ushuaia . At the opening ceremony of the 2012 Winter Youth Olympic Games in Innsbruck , she took the Olympic oath and made international headlines with a mishap: After the first sentence, she got tangled up, and the curse "Shit ..." escaped her spontaneously . In the following races she won the gold medal in the team competition and the bronze medal in the Super-G.
On November 26, 2012, Ager drove for the first time in a European Cup race in Vemdalen , and she received her first European Cup points a week later at the Super-G in Kvitfjell . After she won an FIS race for the first time in January 2013, she achieved her best European Cup placement to date on February 4, 2013 (5th place in the Super Combined by Sella Nevea ). At the European Youth Olympic Winter Festival 2013 in Brașov , she was second in slalom and third in giant slalom. On November 16, 2013, she made her World Cup debut at the Levi Slalom ; Completely surprisingly, she finished fourth with the high starting number 53, only five hundredths of a second behind third-placed Tina Maze . On January 13, 2014, Ager won her first European Cup race with the super combination in Innerkrems .
As she gradually lost touch in her strongest discipline so far, slalom, Ager began to concentrate increasingly on downhill and super-G. This conversion phase lasted around two years. On March 11, 2016, she won a European Cup downhill for the first time in Saalbach . Two more downhill victories at the same location followed in January 2017.
In the 2016/17 World Cup season she was among the points in the downhill runs from Garmisch-Partenkirchen and Jeongseon for the first time in more than two years. In December 2017 she was also able to score points in the Super-G for the first time in Lake Louise with rank 27. After a 22nd place in the second descent on the Tofana , she reached 13th place in the Lenzerheide combination. She had already suffered a partial tear in the inner ligament in her left knee and a bone contusion when she fell in the finish area of the combination Super-G. So she was out for about a month. In 2019 she was nominated for the World Ski Championships in Åre . In the Super-G, she was eliminated.
