16-year old Matthew Hirschberger from the Nation’s Capital Swim Club (NCAP) has broken his 2nd National Age Group Record of the weekend at the NCSA Spring National Championships.
Hirschberger swam a 4:16.43 on Wednesday morning in prelims of the men’s 500 yard free. That breaks the 4:16.59 that was done by Sean Grieshop in 2014 that stood as the old 15-16 standard.
He not only negative-split this race, but he negative-split it by over two seconds.
Comparing that pacing to what Grieshop did at Winter Juniors in December, his first 250 was done in 2:06.9 – more than two seconds better to start than what Hirschberger did. But, whereas Grieshop closed in a 2:09-mid, Hirschberger closed in a 2:07-low. His last 200 yards was an astounding 1:41.3.
In finals, this race becomes a 400 meter long course free, where the 15-16 record is 3:50.68. Hirschberger’s best is 3:56.27.
