September 20, 1942 - first postpartum world record set by Fanny Blankers-Koen

Today is Saturday, September 20, 2025, and on this day in 1942, Dutch phenom Fanny Blankers-Koen set her first world record since becoming a mom 13 months earlier on her way to becoming the Female Athlete of the Century.

 

In this episode we'll learn more about Blankers-Koen, the only woman in history to win 4 gold medals at a single Olympics, and hear why that first postpartum world record was so unprecedented.

 

It is #SaltySaturday, which means that this episode is sponsored by SaltStick. The summer heat is not going anywhere any time soon, which means that we all need to be replenishing electrolytes lost in sweat.

 

The FastChews from SaltStick are my personal favorite way to get electrolytes in mid-run, and they come in some great flavors, plus caffeinated and uncaffeinated versions, too! Listeners of Today In Running History can save 20% off of your order using⁠⁠ this link⁠⁠.

 

AND, as I mention in this episode, SaltStick's sister brand Bonk Breaker is discontinuing their energy bars. Until they are gone for good, you can get a box for free with ANY Bonk Breaker purchase (I love the OMG! Chews) by using the code "ONELASTBOX" at checkout here.
