Maximus Williamson Breaks 13-14 National Age Group Record in 200 Free Wednesday, July 21st – Sunday, July 25th AISD Natatorium, Arlington, TX Courtesy: Shannon Pritchett Maximus Williamson of the North Texas Nadadores has produced a National Age Group Record in the 200 meter freestyle. Williamson swam a 1:53.26 in the 200 free on Friday at the Texas Age Group Swimming Championships (also known as TAGS). That slid him just-under the old record of 1:53.30 that was done at the 2017 Junior National Championships by 1:53.30 Williamson was much more aggressive in his first 100 meters than was Rose, opening the race in 53.44. Rose, by comparison, was faster on the back-half of his swim.
