Lukas Märtens broke Paul Biedermann’s almost 16 -year -old world record over 400 meters freestyle.

The 23-year-old struck the Swim Open from Stockholm after 3: 39.96 minutes. Märtens was eleven hundredths of a second faster than Biedermann at his record in summer 2009.

Märtens is Olympic champion on the route. He had traveled directly from a height training camp in the Sierra Nevada. “I felt good after the altitude training camp and knew that I was in shape – but with such a time I really didn’t expect it”, “ he said: “The world record came as a surprise, I have to let it sink.”

With the historical time, Märtens also put an respect for the world championships. At the highlight of the season at the end of July and early August in Singapore, the Magdeburger is one of the very big favorites.
