 But then... While Ledecky is racing in the water for the USA, the USA could steal this whole thing with Ledecky now. In the final leg, Kate Ledecky, the greatest female swimmer of her generation, gets in the water and closes the distance. I think we may have a change of leader when it comes to the 50 meters to go mark. This is a wild finish at the end of the women's 4x200 freestyle. China have broken Australia, but Katie Ledecky on the charge.
