Youth Stars Challenge Veterans in 400m Freestyle for LA28
With two years until the 2028 Olympics, a mix of established champions and teenage talents are shaping a competitive battle in the men's 400-meter

The race for the 400-meter freestyle podium at the 2028 Los Angeles Olympics is taking shape, with a new generation of teenage swimmers emerging to challenge the event's established stars. Swimming World Magazine reports the dynamic was on display at recent major championships.
Recent Championship Performances
Australian Sam Short, a former world champion, delivered a standout performance of 3:40.52 at the Pan Pacific Championships. That time makes him the fifth-fastest performer in the event's history. At the European Championships, France's Leon Marchand won gold and set a national record with a time of 3:43.14.
German world-record holder Lukas Märtens, the reigning Olympic champion, finished nearly five seconds off his personal best of 3:39.96 at the European meet, clocking 3:44.57. The analysis suggests this performance is likely a temporary setback for the four-time World Championships medalist.
The Rising Teenage Contenders
At least six teenagers are positioned to challenge for spots on the road to LA28. China's 19-year-old Zhang Zhanshuo, the world junior record holder, has already lowered his best time from 3:42.82 to 3:41.55 and is expected to race at the upcoming Asian Games. American 17-year-old Luka Mijatovic, a University of Texas recruit, has broken the 3:44 barrier twice this summer and is seen as the future of U.S. Distance freestyle.
The teenage talent pool extends across Europe. Hungarian 16-year-old Oliver Papai used a strong second half to win the European Championships silver medal in 3:44.46. Russia's reigning world and European junior champion, Grigorii Vekovishchev, owns a best time of 3:44.58.
Event Selection and Development
A key question surrounds German 19-year-old Johannes Liebmann, who recently shattered the world record in the 1500-meter freestyle. While he has a 400-meter freestyle best of 3:44.59, he must decide if he can effectively contest the event alongside the 800m and 1500m distances. Meanwhile, American 19-year-old Ryan Erisman has made significant progress since joining the University of California, Berkeley program, now holding a best time of 3:44.03.
