A meeting with a powerlifter introduced Wildauer to deadlifting and squatting, and by the age of 15 he was deadlifting . He began to compete at the age of 16 years and soon began to set records, thus far having set over 40 national records. He moved into
strength athletics at nineteen, winning his first competition, a qualifier for the Austrian nationals. He then placed 5th at the Austrian nationals, improving to third the following year. In the same year he won the Austrian Winter Giants competition. In 2009 a second place at the
Strongman Fibo classic, behind
Travis Ortmayer, qualified him for the
Strongman Champions League. At his inaugural outing in the league in Serbia, he won the car deadlift and came 5th overall. He went on to compete at the next Strongman Champions League competition in Finland, where he set a new world record in the car deadlift and came 3rd overall. This in turn got him an invite to the
World's Strongest Man. In what was deemed the "group of death" which also contained
Žydrūnas Savickas and
Brian Shaw, he did not manage to qualify for the final. In 2009 he won the Austria's Strongest Man title. Wildauer won the 2010 Austrian Giants competition and 2014 MHP Strongman Champions League. In 2014 he reached his static strength peak and deadlifted raw (in powerlifting standards) at
the Eisenhart Black Deadlift Championships in
Bavaria and broke Hans Strobl's championship record, on his way to become the Eisenhart deadlift champion. At the inaugural 2014
World Deadlift Championships he deadlifted , winning third place, and his lift still remains the Austrian
national deadlift record. In 2015, returning from an
Achilles tendon injury, he won the
Löwenbraukeller Starkbierfest traditional stone lifting competition in
Munich,
Germany and broke the twenty-five year old Bavarian stonelifting world record. He was trained by the German strongman
Heinz Ollesch. ==Personal records==
