Nerding Out: LCM National Age Group Record Progressions

  18 Morgan Priestley | May 01st, 2014 | Club, National, News

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.

    It is crazy to think some records… dated from 2004 and back would still final and some would even Medal at 2012 OG..

  2. bobo gigi says:

    And great swimswam article about Mary T.Meagher

  3. bobo gigi says:

    Mary T. Meagher at the US olympic hall of fame induction ceremony in 2009

    Bobby Hackett and Brian Goodell with Katrina Radke

  5. SprintDude9000 says:

    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.

  6. bobo gigi says:

    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 the women’s 10 and under age category (if she’s still 10 in July and August)
    Winn Aung in the men’s 11/12 age category (perhaps still early because he turns 12 only at the end of July)
    I will also keep an eye on Sophie Housey (crazy fast), Ethan Dang, Kevin Houseman, Carson Foster and Isaac Grinberg in the 11/12 age category.

    Bobby Hackett (age 16) 8:01.54 (split) June 21, 1976 at Belmont Plaza, just looked it up on Wikipedia

  8. Jay ryan says:

    Bobby Hackett set the world record in the men’s 800 free splitting 8:01 at the USA Olympic trials on his way out in the 1500m. That was an official WR so he likely held the NAG for 15-16 at that time and should be in your progressions.

  9. Rafael says:

    Anyone knows of all the record holders how many became individual medalists or world and og individual champions?

    • Braden Keith says:

      Rafael – we’ve got that data as well for a future article. We wanted to make sure we’d caught all of the records first, but Morgan should be working on that next (he had it done for the ones we had, just needs to update with the new names our readers caught).

  10. swammer says:

    The women’s distance free events and IM’s 15-16 year old list is loaded– Hoff, Caulkins, Ledecky, Evans, Cohen, Beisel, Meagher. Also a lot of the men’s 17-18 lists- men’s 400 free and 100 free interesting. Interesting also to see how many times each record has been broken – some many more than others!

  11. Steve Nolan says:

    Love these!

    I was surprised yesterday seeing Ian Crocker being a former record holder in the 200 free, but was like, meh short course! Even more surprised now that he had the long course one, yeehaw!

  12. jswim says:

    Incredible to see just how old the boy’s 13-14 1500 record is.

  13. takealook says:

    in the 200 breast I believe that Josh Prenot held the 17-18 record by beating Cordes at Olympic Trials before Cordes broke it a few weeks later.
