Custer Breaks Sean Grieshop’s 15-16 NAG in 1650 Free at FL Champs: 14:37.86

Florida Virtual Championships – Site 1 (Sarasota)

16-year-old Liam Custer of the Sarasota Sharks completed his sweep of the distance events at the Sarasota site of the Florida Championships by destroying Sean Grieshop’s 1650 free 15-16 National Age Group record by almost 8 seconds, touching the wall with a best time of 14:37.86. This was nearly a minute faster than Custer’s previous best which he set at the YMCA Nationals in April of 2019. Grieshop set the NAG at 14:45.40 in 2014, a record that had stood since 1984 when it was broken by Jeff Kostoff.

Here’s how the two races went down, including their 200 yard splits and 500 yard splits: 

Custer’s Splits Grieshop’s Splits
100 51.64 50.06
200 53.83 (1:45.47) 53.91 (1:43.97)
300 53.88 53.45
400 53.82 (1:47.70) 53.58 (1:47.03)
500 54.13 (4:27.30) 53.99 (4:24.99)
600 53.46 (1:47.59) 53.05 (1:47.04)
700 53.67 53.65
800 53.41 (1:47.08) 53.95 (1:47.60)
900 53.28 53.95
1000 53.49 (4:27.31) 54.18 (4:28.78)
1100 53.48 54.17
1200 53.42 (1:46.90) 54.25 (1:48.42)
1300 53.63 54.32
1400 53.12 (1:46.75) 54.36 (1:48.68)
1500 52.96 (4:26.60) 54.55 (4:31.55)
1600 52.35 (1:45.31) 54.05 (1:48.60)
1650 24.3 25.93
Final Time 14:37.86 14:45.40

 

Custer brought it home in a 24.30 in the last 50 yards, 1.63 seconds faster than Grieshop finished his record-setting race in 2014. Grieshop competed at the 2016 Olympic Trials and is currently a senior at Cal.

With this swim, Custer also set a new LSC record by nearly 30 seconds. The previous record was only 6 years old, set by Nazareno Boscaino at 15:05.90 in 2014. Yesterday, Custer broke the 500 free LSC record as well with a best time of 4:18.49. Custer’s performances this weekend place him at the top of USA Swimming’s 18&Under Winter Championships rankings.

How tall is he? I counted 10 strokes/lap with decent underwaters. Very smooth and efficient.

Before quarantine, Custer’s best time in the 500 was 4:29.92. Today, he went 2-3 seconds faster than that, 3 times in a row, straight. Crushed his old 1650 time by almost a minute. Hard to put into words that he had such a meteoric rise from being mostly unknown to being a NAG holder within a few months.

Here’s a good stat: prior to quarantine, we wrote about Liam Custer twice: once from last year’s state meet, and once at a last-minute Sarasota time trial heading into quarantine.

Since, we’ve written about him 18 times.
