College Swim Times by Age

It is the set of high-school-age times of swimmers who are on Division I mid-major college rosters right now, grouped by age (13–14, 15–16, 17–18) and event. Instead of telling you the time you need, it shows where the swimmers who got there actually were at each stage. It is a reference point, not a prediction or a cutoff.

There is no single cutoff, and it varies by event and division. For any event, the chart shows where current D1 mid-major swimmers stood at 15–16 (roughly sophomore to junior year): the median time and the middle-50% range. Read it as where those swimmers were at that age, not a bar you must clear.

For this cohort the median times get faster from 15–16 to 17–18, but the size of the drop shrinks with age, the biggest improvements tend to come earlier. Some swimmers make a large jump and some hold about steady. The page shows the typical cohort change as a reference, never a guarantee for an individual swimmer.

Roughly: 13–14 is 8th to 9th grade, 15–16 is sophomore to junior year, and 17–18 is senior year plus the following summer. These bands match the standard USA Swimming age groups, which is why they line up cleanly with age-group results.

It is early, and a lot changes between 13 and 18. The 13–14 band is best read as orientation, a sense of where current college swimmers stood that young, not a verdict. Development, growth, and training all move times a great deal across high school.

From the high-school-age personal-best times of swimmers who are currently on Division I mid-major rosters, for the 2025–26 season. Every cell is built from at least 30 swimmers, and only aggregate percentile bands and counts are shown, never individual swimmers. More divisions are coming.
