310. The Fatigue Resistance Episode! Rachel Entrekin Makes History at Cocodona, Women v. Men Durability, Fueling and the Central Nervous System, Brain Changes, and More

5/12/20261 hr 34 min

We had some HYPOTHESES for this amazing episode! The main topics all revolved around fatigue resistance (often called “durability” in the literature), which we think is the most exciting area of training theory and physiology. It started with Rachel Entrekin’s legendary overall win at the Cocodona 250, an event that explores some of the strangest and coolest parts of endurance.

Our big theory: what we’re seeing in these wild ultras is directly connected to what we see in short distances. A new study looked at fatigue resistance variations between men and women, with some shocking results. We expand the scope to talk about the literature generally before going to some ideas for how it all might relate to the central nervous system.

...And how it relates to fueling. You could probably guess that we were going to talk about carbs.

Plus, we answer questions about the culture of fueling for young athletes and feeling good after long runs!

This one starts with a description of Megan’s health journey. The hottest vacation is apparently a 3-day stay in Boulder Community Hospital. Things are scary, but we’re holding onto hope for the future.

We love you all! HUZZAH!

    Woo.

  2. David Roche· Host0:01

    Woo. Welcome to the Some Work All Play podcast. We are so happy to be with you today.

  3. Megan Roche· Host0:04

    Happy Tuesday.

  4. David Roche· Host0:05

    It's Tuesday.

  5. Megan Roche· Host0:05

    And we're bringing our best gems on this Tuesday.

  6. David Roche· Host0:08

    Our best gems. What are you talking about?

  7. Megan Roche· Host0:09

    I'm holding up my wrist.

  8. David Roche· Host0:10

    Oh, yeah.

  9. Megan Roche· Host0:11

    You got me a Mother's Day gift. It is beautiful. [laughs] [laughs] We got it up at the farmers market in Nederland.

  10. David Roche· Host0:16

    I did ask Megan yesterday, I'm like, "Is it okay that I didn't get you anything for Mother's Day?"

  11. Megan Roche· Host0:20

    I was like, "Absolutely."

  12. David Roche· Host0:21

    [laughs] Yeah.

  13. Megan Roche· Host0:22

    Yeah.

  14. David Roche· Host0:22

    [laughs] Okay, so we end- ended up going to the farmers market, and you were picking out bracelets. I was like, "Megan, treat yo self, girl."

  15. Megan Roche· Host0:28

    You know, I- I stepped up ... those bracelets over there are beautiful. And I was like, "Look at you assessing women's jewelry."

  16. David Roche· Host0:33

    Yeah, this is my, my jam. I know this so well.

  17. Megan Roche· Host0:36

    So we were picking through all the bracelets. I've got a tiny ass wrist, and so- Yeah ... it kind of narrowed the selection of bracelets. And they all had these, like, circular, what do you... I guess beads.

  18. David Roche· Host0:45

    Yeah.

  19. Megan Roche· Host0:45

    And they all mean something. We really did not look into this much. [laughs] [laughs] And so we picked one out. I was like, "I think this one's beautiful."

  20. David Roche· Host0:51

    Yeah.

  21. Megan Roche· Host0:52

    You were like, "I agree, Megan. That's my favorite."

  22. David Roche· Host0:53

    The main meaning you wanted was, is this sexy as fuck? And it was.

  23. Megan Roche· Host0:57

    [laughs] Yeah.

  24. David Roche· Host0:57

    It was so sexy. Um, but as we were checking on it, what is the meaning of this one? And it's mostly green orbs, I would call them, around the outside.

  25. Megan Roche· Host1:05

    And then one beautiful pink little guy- Yeah ... hanging out in the middle. And so we brought it up and we asked them. And they said, "The green ones are for healing and the pink one is for heart." And boom.

  26. David Roche· Host1:14

    Boom.

  27. Megan Roche· Host1:14

    I almost cried on the spot.

  28. David Roche· Host1:15

    [laughs] Heart healing. Uh, okay, so we're talking about that because last week you may have heard some rumblings as we recorded, where we're like, "Oh, our life is a crap storm," and all this other stuff. And I had... was making Megan record that right before we
