Ayden Tan Adds Multiple 11-12 NAG Records to Resume
Ayden Tan (SRVA) continued his steady rise through the age‑group ranks with another record‑setting swim in California. This month, he added a new line to the record book and moved the standard forward.
At the 2025 TYR GO International Challenge in Fresno, Tan clocked 2:12.80 in the 200‑meter individual medley. With that swim, he lowered the boys 11–12 National Age Group record. Richard Poplawski set the previous mark, 2:13.59, in 2019.
The new time now stands as the fastest 200 IM ever recorded in the age group. Moreover, it improved the national standard by nearly eight‑tenths. For a four‑stroke event at this level, that margin is significant.
Tan (SRVA) trains in Pacific Swimming with San Ramon Valley Aquatics, where coaches emphasize precision and pacing. As a result of his training, he continues to execute controlled, technically sound races across all four strokes.
Looking ahead, Northern California’s schedule features Far Westerns and the Western Zone Championships. If Tan maintains this form, further drops seem possible. Even so, this record already underscores a remarkable season for the SRVA standout.
