🇺🇸 Katie Ledecky was unstoppable at the 2015 World Championships in Kazan! ⏱️ 15:25.48 in the 1500m freestyle...

This is the longest race on the books. The 1500 meters freestyle final for women and it's Van Ruendael of the Netherlands across in lane one, Boyle of New Zealand in two, Ashwood Australia three, then it's Ledecky and Fries in four and five, Cobbridge of Chile, Capas of Hungary and the Italian Poncelli who as I mentioned certainly in the open water program takes it out very hard but I think we know who's going to take it out the hardest here. That is Katie Ledecky who leads after the first 50 and already the lead is about three quarters of a second of Fries and Ashwood and she's 0.19 under the world record split at the 50 but that could just be the adrenaline from the start kicking in. She's been under world record pace from the first 50 and she's heading for another gold medal and it would seem another world record in the 1500 meters as she goes up now with 150 meters to swim. We'll watch the clock there. She slowed it down just a little. She's still inside world record pace 1.87. It's Boyle of New Zealand second and Fries of Denmark third and then follows Ashwood of Australia. Tremendous swimming here for Katie Ledecky. The crowd is trying to encourage her to get onto this final 100 meters. Still not brought her in. American fans are cheering from the stands. The Russian fans are cheering from the stands. Go on Katie. 100 meters to go. She gets the bell and she's still almost two seconds under world record pace. Katie Ledecky the remarkable 18 year old American. She's already the gold medalist in the 400 meters here in Barcelona. She won the 400. She won the 800 and she won the 1500. She lowered two world records. She went on to London and she won the 800 there and now this looks like another world record coming her way as she turns at the 14.50 inside the last lap and Katie Ledecky is heading for a gold and another world record. The Americans cheering her on. Boyle placed for second. Fries for third but it all lies on the 18 year old Ledecky. The world record line at her feet. She goes in now with five to swim and Ledecky is going to smash the world record in the 1500 meters. Another gold, another world record. How good is she? Fantastic. So I've got goosebumps watching that finish. But it is all about Katie Ledecky here. Another world record. Katie Ledecky. The unstoppable Katie Ledecky.
