It hasn’t happened since the 2016 Olympics. Katie Ledecky hadn’t broken a World Record since 2016 when she lit the world on fire in Rio with three individual gold medals and two world records. She has not been the same swimmer since she went to Stanford in the fall of 2016.

But in her first race as a professional swimmer, Ledecky broke the 1500 freestyle World Record that she set at the 2015 World Championships in Kazan with a 15:20.48 on a quiet Wednesday night at the TYR Indianapolis Pro Swim Series.

Ledecky took control early and was out under world record pace. How long could she hold on to that pace in an in-season meet? She built her way through the race and kept getting further and further under the record pace.

Ledecky broke her own world record that she set three years ago and is the sixth time she has broken the record in the event dating all the way back to 2013. It is also the largest margin the record has been broken since Ledecky took six seconds off at the 2014 Pan Pacific Championships.
