Nerding Out: LCM National Age Group Record Progressions

Yesterday, we published our SCY National Age Group record progression list, and got a ton of great feedback (thanks to all who helped!).  Today, we’re posting our LCM NAG record progressions the same way we did yesterday.

Once again, we have embedded a spreadsheet below from all of the existing data we have available.  In addition, we included the swimmer’s total number of Olympic medals in the righthand columns.

We’re expecting there will be a couple errors like there were yesterday; as we previously stated, our resources were limited (available meet results online, USA Swimming’s time databases, and existing USA Swimming top 100 documentation).  See any errors or omissions?  Feel free to leave them in the comments section, and we’ll address them/extend our gratitude for the assistance.


Again, if we look at the number of Olympians like we did yesterday (counting each swimmer once per age group):

Age Group Number of Olympians (LCM)
11-12 girls 10
13-14 girls 15
15-16 girls 20
17-18 girls 27
11-12 boys 1
13-14 boys 6
15-16 boys 17
17-18 boys 27


For comparison, here’s the chart from yesterday’s SCY progressions (with one change, due to the addition of Elaine Breeden in the 17-18 girls 200 fly):

Age Group

Number of Olympians

11-12 girls


13-14 girls


15-16 girls


17-18 girls

11-12 boys


13-14 boys


15-16 boys


17-18 boys



We’ll do more analysis on this later, but the most interesting thing as first glance is that for the 13-14 and 15-16 age groups, the number of age group record setters in long course meters who went on to be Olympians is actually less than the totals in short course yards.  While the LCM numbers surpass the SCY ones in the 15-16 and 17-18 age groups, you would think that, given just how different the two courses are, we would see more LCM record holders turning into Olympians at a younger age.

Stay tuned for our multiple-entry NAG record listings.  They’re quite a bit more involved (we’re attempting to count every instance a record was broken, although we’re missing a lot of data from the 70’s and 80’s), so expect them either this weekend or early next week.

Awesome article. It would interesting if SwimSwam could catch up with some of these legendary age groups now and discover where their swimming/lives have taken them thus far.

Again, great job!
I don’t see many errors.

Sippy Woodhead at 14 in 1.58.53 in the 200 free in 1978!!!! It’s amazing!
Like Mary T.Meagher’s times on butterfly in 1981.
Or Bobby Hackett and Jesse Vassallo in the distance events.

In my opinion the best contributors to break NAG records next summer in long course will be :
Katie Ledecky, Simone Manuel and Missy Franklin in the women’s 17/18 age category
Reece Whitley in the men’s 13/14 age category
Cassidy Bayer in the women’s 13/14 age category
Regan Smith in the women’s 11/12 age category
Caeleb Dressel in the men’s 17/18 age category (if he swims next summer)
Meghan Lynch in… Read more »
