Lukas Märtens backed up his pioneering sub-3:40 World record of 3:39.96 over 400m freestyle in Stockholm last month with a 3:40.61 victory on the opening day of the German Championships in Berlin.

Having rubber stamped his ticket to the World Championships in Singapore in July, the 23-year-old Olympic champion, coached by Bernd Berkhahn at the Magdeburg performance centre, acknowledged the impact of his World record in Sweden:

"I don't think I've ever seen such a full house in Germany. Maybe last year [Olympic title] had a bit of an impact. I hope the trend continues, with more and more people becoming aware of swimming again."

They're sure to if there's more of this in a country that boasts the biggest membership of a swimming federation in the world:

What it took for Lukas Märtens to break Paul Biedermann’s Word record: at 51.90 he matched Mark Spitz’s first 100m free World record in 1970; at 1:47.55, he matched the third of Michael The Albatross Gross’ 200m free World records, from 1984

Märtens was delighted to have backed up his world record with the third fastest time of his career after that 3:39 and the 3:40.33 warning he delivered at German nationals a year ago on the way to the Paris 2024 crown. He said:

Speaking through the DSV's Swim&More, he said:

"Two races like this within three weeks – that's something you have to be able to do, so I'm very satisfied. To be honest, I didn't expect that myself. But it's all the better that we're back in the running. Let's see how things go in the summer."

It was a race of training partners. Closest to Märtens was Oliver Klemet, the Paris 2024 Marathon silver medallist: tipped by SOS to grab the second Germany berth for Singapore, he did just that: his 3:43.40 kept 2020ne Marathon champion Florian Wellbrock at bay, on 3:45.29, while the fourth contender, Sven Schwarz, clocked 3:46.71, inside the 3:47 cut for Singapore and left his bid there.

Klemet said: "I'm very satisfied. Just a few days ago, I did the 10km and the open water knockout race [which he won], which took a lot of energy. That's why I'm glad I was able to swim so fast again."

Märtens, meanwhile, paid plaudits to his coach and he way he has been elevated to his current status in a steady season-by-season process:

"For me, Bernd is the best coach in Germany, if not in Europe. I was slowly guided to the world elite, to the top level. I'd say I've established myself there now, and that's been further confirmed by a time like that today."
