The U.S. were the defending champions but only Allison Schmitt, who swam the leadoff leg in Rio, was in the race lineup from that London 2012 golden quartet.

Leah Smith and Maya DiRado swam second and third respectively before Ledecky - who won the 400 freestyle on Sunday and 200 free on Tuesday -- brought home the gold.
