Summary
We cornered the market on mozzarella sticks before this awesome episode! The main topic involved our recommendations for electrolyte use in races and hard training. Sweat replacement is one of the strangest, least understood parts of athletic physiology. We give our guidelines from lots of real-world experimentation.
And this one was full of incredible topics! Other topics: the happiest place on Earth, Megan’s first video filming and the year of vulnerability, David’s return to run, a new probiotic study showing the weird connection between the gut and brain, Kristian Blummenfelt measuring with the highest VO2 max ever (or did he?), Airpod 3 heart rate, gambling in running, Truett Hanes’ OTQ chase, our updated thoughts on applying AI in training, a Nomio follow-up, the perils of setting Z2 in the wrong place, changing directions on the track, elliptical v. bike training, bike cadence, a deep question on parenting, and lots more!
Whenever you’re in doubt about our place in the Universe, look up at the night sky, take a deep breath, and give the universal signal: SUCK IT.
That will make a bit more sense soon (maybe). We love you all! HUZZAH!

| 0:01.0 | Welcome to the Some Work All Play podcast. We are so happy with you today. Happy Tuesday. It's Tuesday. And I'm ready to get my spin on on this Tuesday. Get your spin on. We're talking about biking? Talking about the carousel. Oh my goodness. Talking about some typical forces that might be too much for me. I'm so happy you're starting with this because this weekend, we went to the carousel of happiness in |
| 0:21.9 | Northern Colorado. And this is a visit to David's Hope Corps Corner because I went in there. And I was |
| 0:27.6 | just filled with so much joy from like a cellular level on out. And it's so important that we |
| 0:32.4 | bring this to the people. This is a hand-painted carousel. And we walk in and they told us all |
| 0:37.1 | about it, including that it was a 501c3 and their |
| 0:40.1 | primary goal behind being a 501c3 is to spread joy. |
| 0:42.9 | We're all about it. |
| 0:44.8 | I love it so much. |
| 0:45.6 | So the backstory here is actually so beautiful. |
| 0:48.4 | So Scott Harrison was in Vietnam and he had a music box that he played into his ear just to deal with the horrors |
| 0:55.6 | of war. |
| 0:56.4 | And when he came back to deal with the PTSD of it, he spent 26 years hand carving animals |
| 1:02.8 | one by one. |
| 1:03.7 | And these things are beautiful. |
| 1:04.5 | He had never carved before. |
| 1:06.1 | And then the town of Netherlands and Colorado raised $700,000 to create the carousel. And you step in, |
| 1:12.4 | and it's just full of the most, like, beautiful vibes you've ever felt. I feel like everyone |
| 1:17.4 | in there is joyful. The person operating the carousel at one point, I saw her, she just got on an |
| 1:21.9 | animal and had those big noise-canceling headphones and was just rocking out. And she was dancing |
| 1:26.7 | and bliss out beyond belief. Yes, it's Netherlands, Colorado. So there probably was some chemical assistance. I was like, there must be chemical assistance here. Oh, my God. And as I was in there, I was thinking, all right, carousel of happiness, a good mission to have. But maybe more true to our times would be carousels of other types of emotions. That's a pair. |
| 1:44.5 | Did you think about this at all? Well, I was thinking, I was like, what else we put on a carousel? And I feel like to me, the act is like selecting what you want to ride. And so I was thinking of all the different things that would be fun to parse out, like donut flavors or books or different things. So for me, it's like the act of picking which one you're going to ride. I'm kind of hung up on it's the act of picking what you want to ride. |
