Mads Glæsner
Mads Glæsner is a Danish swimmer. He participated at the 2008 Summer Olympics in the 400 metre freestyle and the 1500 metre freestyle disciplines. His swimming club is Vallensbæk-VAT but he trains at the National Training Center in Copenhagen.
He competed at the 2012 Summer Olympics in the 400 m freestyle and the 4 x 200 m freestyle relay.
In June 2013, Glæsner was stripped of a gold and bronze medal from the 2012 World Short Course Championships after testing positive for levomethamphetamine.
However, upon appeal to the Court of Arbitration for Sport, Glaesner's 1500-metre freestyle gold medal was reinstated based on the fact that a test after that race, two days after his initial positive test following the 400-metre free, was clean. He still forfeited the 400-metre freestyle bronze, which he did not appeal.
Since then, he has competed at the 2016 Summer Olympics, in the 400 m freestyle.
