Miriam Sheehan Destroys 100 Yard Back NAG At Final Meet As 10&Under

Phoenix Swim Club’s Miriam Sheehan is in her very last meet as a 10-and-under, but she got in just one day before her birthday, destroying the 100 yard backstroke National Age Group (NAG) record by almost two seconds.

Sheehan went 57.96 to win the 100 back at the 2015 Fall Meet #1 in Paradise Valley, Arizona, breaking the NAG record by a wide margin.

Sheehan turns 11 tomorrow, but gets to swim out the remainder of this meet in the 10&Under age group.

Today’s result gives her three short course NAGs in the 10-and-under bracket to go along with her five long course records.

She breaks the old 100 back NAG of 59.89 set by Regan Smith back in 2013, taking nearly two seconds off that time. Her 50 split of 27.76 – to her feet at the flip turn – would have broken Smith’s NAG as well, had Sheehan not already taken down that mark last weekend. Smith’s record was previously 27.79; Sheehan went 27.27 last week.

Sheehan now owns 10-and-under short course NAGs in the 50 fly, 50 back and 100 back. She holds long course records in the 50 free, 50 back, 100 back, 50 fly and 100 fly.

She swam (and won) the 100 free and 50 back earlier in the meet, just missing her NAG with a 27.33 in the back and going 55.53 in the free.

She’ll swim the 100 fly, 50 fly and 200 IM later on in the meet.
