Split Time for the 1500M Freestyle is sponsored by LumaLanes.

Today we look at the 1500M Freestyle splits by analyzing the current World Record set by Sun Yang at the London Olympics in 2012 and compare those splits to the World Junior Records set by Mack Horton in 2014 and most recently by Franko Grgic on August 25, 2019

Sun Yang: 14:31.02  August 4, 2012, London

55.80; 1:54.31; 2:52.63; 3:51.50; 4:49.62; 5:48.15; 6:46.74; 7:45.45; 8:44.32; 9:43.10; 10:41.73; 11:40.64; 12:39.00; 13:37.53; 14:31.02 (27.81; 25.68 = 53.49)

Mack Horton: 14:51.55 – Old World Junior Record, April 1 2014, Brisbane

56.71; 1:56.33; 2:55.77; 3:55.25; 4:55.10; 5:54.19; 6:53.57; 7:53.63; 8:53.70;  9:53.67; 10:53.55; 11:53.74; 12:53.83; 13:53.81; 14:51.55 (29.05; 28.69 = 57.74)

Franko Grgic: 14:46.09 – Current World Junior Record, August 25, 2019, Budapest

56.52; 1:55.88; 2:55.57; 3:55.53; 4:54.84; 5:54.31; 6:53.66; 7:53.07; 8:52.49 ; 9:51.66; 10:50.93; 11:50.21; 12:49.43; 13:48.71; 14:46.09 (29.09; 28.29 = 57.38)

Analysis

If you break down the race as 3 x 500, Horton and Grgic were over 5 seconds off Sun’s first 500 pace.  Grgic had only a .26 second lead over Horton at the 500 mark.  At the 1000 mark, Grgic pulled out in front of Horton by over 2 seconds (2.01) but fell behind Sun by 8.56 seconds.  The final 500 saw Sun extend his lead to 15.07 seconds with a blistering 53.49 for his final 100 meters.  Grgic came home in a 57.38 over Horton’s 57.74 to set the World Junior Record and by 5.46 seconds.
Sun’s 500 Splits:   4:49.62, 4:53.48, 4:47.92
Horton 500 Splits:  4:55.10, 4:58.57, 4:58.88
Grgic 500 Splits:    4:54.84, 4:57.82, 4:54.43
For Grgic to break Sun’s World Record, it appears that he would have to take out the first 500 much faster and hold pace for the middle and final 500.  The real kicker would be the last 100 meters.  Sun’s last 100 was smoking fast.  His second last 50 was 1.2 seconds faster than the field and his his last 50 was 3 seconds faster than Horton and 2.61 seconds than Grgic.  Sun was on fire!
Basically, if anyone wants to break Suns World Record but cannot bring it home like Sun, they would have to Even split the 500’s at 4:50.50
