Katie Ledecky is back where she’s comfortable.

Day 2 of the 2021 Pro Swim Series in Mission Viejo saw Olympic champion Ledecky tie the U.S. Open record in the 200m free in a time of 1:54.40 and take the No. 1 spot in the world rankings.

It’s Ledecky’s best time ever on U.S. soil and her second-best performance ever in the event. Her lifetime best 1:53.73 won her gold in the event at the Rio Olympics in 2016.

Notably, Ledecky is faster than she was four years ago in the U.S. Olympic Trials when she swam a 1:54.88. One can only wonder what she’ll be capable of come Tokyo.
