Extreme Endurance: How Lindsay Phenix Ran and Recovered from 30+ 100-mile Ultras

Lindsay Phenix is the winner of the 2026 Badger 100, a finisher of more than 30 100-mile ultramarathons, and two-time finisher of the Badwater 135.
In this episode, she shares what it takes to have this kind of consistency and durability:
How she prepares for so many 100's so frequently (about 4 per year!)
What her training looks like in between major events
What makes the Badwater 135 so unique
Why the 100-mile distance is so captivating (and why you should run one too!)
Thank you Lindsay!

When I'm not wearing their classic long sleeve shirt as a base layer, I'm running in it. What really makes Cozy-Zero special is that they use 15.5-micron ultra-fine merino wool, which is softer than cashmere.

Thank You MOBO Board!
Invented by renowned physical therapist Jay Dicharry, MOBO helps you stabilize your stance with an innovative rocker board that's set up on two fins. The design effectively forces you to drive your big toe into the board to improve your stability. I was pretty arrogant going into my first session on the MOBO Board. How hard can it be to balance, right? Well, I was humbled pretty quickly!
Even if you're a good runner, better balance, stability, and proprioception is going to help you have a more powerful stride and prevent more running injuries. You'll learn how to improve the efficiency of the kinetic chain from your hip to your big toe. Because as Jay likes to say, it's not just how strong you are, but how well you use that strength.
I was recently at a weekend physical therapy workshop (lol I was the only running coach) and learned how important (and rare) this simple movement is. Save 10% with code STRENGTHRUN10 at checkout at moboboard.com.
