Katie Ledecky: Arena Pro Mesa, Day Two Finals

​Katie Ledecky ​had an impressive double on night two at the arena Pro Swim Series at Mesa -- taking second in the 400 IM with a 4:38.16 and first in the 200m freestyle with a 1:56.31, the fourth-fastest time in the world this year.​

Ledecky answered the question everyone was wondering: she is only competing in the 400 IM for training purposes. She mentioned in her interview, "the last 100 of a 400 IM is good practice for the last 100 of a 400 free."
