All The US No. 1s From This Past Week (Feb. 18-24)

* Anna Hall broke the national record in the high school pentathlon on Friday in New York

- - - 

It was an eventful weekend, wouldn't you say? 

A high schooler set an American Record, a World Junior Record, a U18 Youth Record, a World Lead and a national record -- all in one race. Another national record was broken the day before. Three more all-time efforts went down at various distances. 

And then we had all the US No. 1s that took place, too. 

Soooo was kind of crazy. Check out all the great performances below.
