Cain posted a 4:14.77 in the prelims of the 1500 at the World Junior Championships to automatically qualify for the final. Just .27 off of the HSR.
I know she's already run 4:14 this year, but that's another great time and shows she's still in peak shape. Hopefully she can rest up and drop a few seconds in the final. And she's still only a sophomore! She'll have another chance at World Juniors in two years.
