A group of 15-18 boys from SwimAtlanta in Atlanta, Georgia combined to break the National Age Group Record in the 200 yard medley relay on Sunday afternoon.
The team of Collin Holgerson, Camden Cook, Gavin Halusic, and Connor Christopherson combined for a 1:25.63. That knocked three-tenths of a second off the old record of 1:25.94 set by a group from the Nashville Aquatic Club in 2024.
Splits Comparison
| SwimAtlanta | Nashville Aquatic Club | |
| New 15-18 NAG Record | Old 15-18 NAG Record | |
| Back | Holgerson – 20.86 | Blake Amlicke – 21.57 |
| Breast | Cook – 24.30 | Mack Schumann – 24.25 |
| Fly | Halusic – 21.21 | Spencer Nicholas – 19.95 |
| Free | Christopherson – 19.26 | Todd Dong – 20.17 |
| 1:25.63 | 1:25.94 |
The difference-making splits for SwimAtlanta were USA Swimming Junior National Team member Holgerson on the leadoff and Christopherson on the anchor.
That’s a new personal best in the 50 back for Holgerson, and would have been the 9th-fastest split in the 200 medley relays at last year’s NCAA Championship meet.

Holgerson also won the 100 breast (51.75), 100 fly (46.82), 200 back (1:40.29), and 200 breast (1:53.63) at the meet, and finished 2nd in the 50 free (20.15) behind Christopherson (20.00). The 100 breast, 100 fly, and 200 breast were all lifetime bests for him, with the 200 breast being a 5.8 second improvement in a non-primary stroke for him.
All four swimmers are high school juniors, with Holgerson attending the McCallie School in Chattanooga, though he represents his home club SwimAtlanta in USA Swimming competition.
- Holgerson – Tennessee (2027)
- Cook – Georgia (2027)
- Halusic – Arizona State (2027)
- Christopherson – Stanford (2027)
They are all 17, meaning they also break the 17-18 National Age Group Record, which was the same relay that previously had the 15-18 record. The Mason Manta Rays still hold the 15-16 record in 1:28.85 (Carson Foster, Ian Van Gorp, Jacob McDonald, and Adam Chaney).
While the meet’s proper schedule only had mixed relays, age group coach Michael Mahroum recognized the possibility of the record and coordinated the time trial session.
This is the second 15-18 National Age Group Relay Record set this weekend. Central Ohio Aquatics broke the 200 free relay on Thursday.
Awesome job guys!!! great swimming all around!
insane fly split
Three C’s and a G!
Congrats! I heard Halusic & Christopherson both turned 17 very recently. Impressive group of young swimmers!
Halusic is going to ASU not Georgia. Also, Holgerson wasn’t the winner of the 50 free. That was Christopherson, who also won the 100 and 200 free.
Yeah Gavin’s going to ASU. They’re very lucky to get him.
Second time in a week.
Congrats Boys!
