With their runner-up finish in the women’s 400 medley relay, the TAC Titans team of Reina Liu, Carolin He, Nikki Nixon, and Sloane Whelehan downed the girls’ 15-16 National Age Group record in the event, previously held by Virginia Gators at the 2017 Dolphin ISCA Junior National Championship Cup in 3:36.53, with their final time of 3:34.53.
That relay of the Virginia Gators comprised of 20-time NCAA All-American Olivia Bray (Texas), three-time ACC Champion Emma Muzzy (NC State), Whittney Hamilton (Tennessee), and Caroline Kulp (Virginia).
Liu led off in 52.04, just slower than the previous NAG record’s opening leg from Bray in 52.02. The 2017 relay also held the advantage through the backstroke leg as well, with Muzzy out splitting He by just over three-tenths (1:01.91 to 1:02.25).
The major disparities come in the back half of the race; Nixon’s fly leg of 51.43 outpaced Hamilton’s in 2017, 51.43 to 53.03, a 1.6-second difference on that leg alone.
Wheelan’s anchor leg of 48.71 was nearly a full second faster than Kulp’s 2017 relay anchor of 49.57.
Splits Comparison
| Leg | TAC Titans (3:34.43, 2025) |
Virginia Gators (3:36.53, 2017)
|
| Back | Liu – 52.04 | Bray – 52.02 |
| Breast | He – 1:02.25 | Muzzy – 1:01.91 |
| Fly | Nixon – 51.43 | Hamilton – 53.03 |
| Free | Whelehan – 48.71 | Kulp – 49.57 |
| Final Time | 3:34.43 | 3:36.53 |
At this meet, TAC Titans finished just over half a second (.55) from Mecklenburg Swim Association, who went on to win the event.
The same 2017 quartet of Muzzy, Kulp, Bray, and Hamilton still holds the 15-16 NAG 200 medley relay record.

Impressive splits !!
curious question:
To qualify as an NAG (National Age Group) record, must every swimmer be a US citizen? (Ie from the same nation)
Yes, though there’s no rule that requires them to be a US sporting citizen.

Does anyone have any insight if Reina is going to continue to try to represent Canada internationally? Was surprised to not see her at Trials last summer when she would have likely made WJs
Wasn’t she part of the latest list of carded athletes released by swimming Canada?
I don’t, but I can ask. They made it much, much easier for juniors to flip-flop sporting citizenships, so nothing set in stone…
I see where you are coming from. Liu is Canadian, so let’s hope the parents have her birth certificate handy and not run into a Kharun stunt.
