BUDAPEST, Hungary — The short-course swimming world championships in Budapest witnessed an impressive display of athleticism on Tuesday, as numerous world records were broken, particularly by the U.S. relay teams, both men’s and women’s.

Gretchen Walsh played a pivotal role for the U.S. women, leading her team to secure the gold medal as well as a world record in the 4×100-meter freestyle relay. They achieved a remarkable time of 3 minutes, 25.01 seconds, with Walsh having already set the bar high earlier in the day by breaking the world record in the women’s 50-meter butterfly not once, but twice.

On the men’s side, the U.S. team also dazzled, finishing the 4X100-meter freestyle relay with a new world record time of 3 minutes, 1.66 seconds, surpassing competitors Italy and Poland.

In addition to the relay events, several individual swimmers made headlines by breaking records as well. Eighteen-year-old Canadian sensation Summer McIntosh set a new standard in the women’s 400-meter freestyle, while American Kate Douglass claimed a record in the women’s 200-meter medley. Swiss swimmer Noe Ponti also made waves, breaking the world record in the men’s 50-meter butterfly.

The championships take place in a 25-meter pool, which is half the size of the standard Olympic pool, presenting unique challenges and opportunities for the competitors.
