The Carmel Swim Club of Carmel, Indiana led 4 teams under the old SC Juniors overall Meet Record, and eventually came away with the mark in 6:28.25. That also broke the old 15-18 National Age Group Record in the event that was a 6:28.90 set by SwimMAC Carolina in 2013.
The Nashville Aquatic Club bettered the 15-18 National Age Group record, but with 14-year-old Gretchen Walsh on the team, the record doesn’t officially count.
