A big thanks to LMNT for their support of this episode! They make electrolyte drinks for athletes and low-carb folks with no sugar, artificial ingredients, or colors. They are offering a free gift with your purchase at LMNT. And this does NOT have to be your first purchase. You'll get a sample pack with every flavor so you can try them all before deciding what you like best.

And DOUBLE big news! Their newest flavor Lemonade Salt is now permanently available (it's now my favorite). They're also offering 12oz cans of sparkling LMNT water that has half the sodium concentration of a packet. Check them out.

LMNT's products have some of the highest sodium concentrations that you can find. Anybody who runs a lot knows that sodium, as well as other electrolytes like magnesium and potassium, are essential to our performance and how we feel throughout the day.

LMNT is my favorite way to hydrate. I'm now in the habit of giving away boxes of LMNT at group runs around Denver and Boulder and everyone loves this stuff.

Boost your performance and your recovery with LMNT. They're the exclusive hydration partner to Team USA Weightlifting and quite a few professional baseball, hockey, and basketball teams are on regular subscriptions. So check out LMNT to get a free sampler pack and get your hydration optimized for the upcoming season.

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!

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.

"My ankle and knee pain was completely gone in a week. Amazing!" - Kim

"I thought I was on the verge of having to give up running due to severe hip pain and luckily discovered Previnex - complete game changer for me!" - Anna

"I am so grateful for Joint Health Plus! As a certified fitness professional and still an extremely active, competitive amateur athlete, I was getting discouraged with an increase in pain simply kneeling down, or bending down to the floor and getting back up while assisting clients, or in my own training! Once deciding to give this product a try, I was floored when I finally noticed I was not bracing in anticipation of pain when I had to kneel down; not whincing in discomfort upon standing! Thank you, Prevenix!" - Jessica

Joint Health Plus is so powerful because the main active ingredient is clinically proven to reduce joint pain, reduce joint stiffness, and improve joint flexibility in just 7-10 days. It's also clinically proven, not just tested, but actually proven in double-blinded, placebo- controlled studies to protect joint cartilage from breaking down during exercise.
