Katie Ledecky gave NCAP their 4th National Age Group Record of the weekend with a 15:28.36 in the women's 1650 in Austin.
That obliterated, by 12 seconds, her old record of 15:40.38 at the NCSA National Championships.
This was a classic Ledecky swim. After opening in a 52.3, she swam 56′s on each 100 straight through, save for a 55.99 and a 57.2 on her 12th hundred.
The 2nd-best swimmer in the history of this age group is still Kate Ziegler in 15:40.89. Ledecky is only 4 seconds from the American Record. Ledecky trains at a different site than NCAP's other two record breakers from this weekend, Andrew Seliskar and Janet Hu. Training under her new coach Bruce Gemmel seems to be going well initially.
