When you get a new smart watch, heart rate monitor, or other type of wearable, do you know how it will help your running, specifically?

Dr. Peter Tierney is a health and performance researcher, consultant, and coach who's worked with many professional sports organizations across Europe. He joins us today to discuss the science behind wearable tech.

We discuss:

• The wearable stack that Peter recommends
• Most important metrics to focus on
• Recommended hardware (specific products)
• What you can safely ignore
• Why the actual metric may not be as important as the trend over time

Peter first joined the podcast in 2024 to discuss the 5 Big Recovery Strategies (listen here).

Thank you Previnex!

After resisting most supplements for the better part of my life, I'm cautiously changing my tune. I'm now a Masters runner and in my personal life, I'm optimizing for longevity. I want to be my healthiest self for as long as possible and I'm excited to partner with Previnex to make that happen.

Previnex uses the most bioavailable, clinically tested ingredients, the optimal form and dose of each ingredient, pharmaceutical grade manufacturing, testing of raw ingredients and finished products. For every purchase you make, they also donate vitamins to kids in need.

Their new Muscle Health Plus is something I'm now taking. Turning 40 – and having a thin frame – has made me realize that I need to prioritize lean muscle mass to stay healthy and age well. Muscle Health Plus has creatine, essential and branched chain amino acids, and it's designed in a way to maximize protein synthesis and the absorption of amino acids.

Muscle Health Plus will help you prevent muscle damage, which is particularly important for aging runners who want to protect themselves from muscle loss and recover faster after hard workouts. As is true for all of their products, Previnex adheres to the highest of standards: their ingredients are clinically proven to do what they say they're going to do.

They're now offering international shipping so if you live in the UK, Canada, Australia, or anywhere around the world, you can try Previnex as well.

Previnex offers a 30-day money back guarantee. If you don't feel the benefits of their product, you get your money back no questions asked. With their focus on quality and customer satisfaction, I hope you'll try it!

Thank you Avelo!

Avelo is the world's smartest running shoe created by a team of ex-Nike engineers. I'm so excited by Avelo that I've been advising them for nearly two years. And the market has spoken - they raised over $100,000 on Kickstarter on their very first day because they're doing something unique.

Embedded in their bouncy, lightweight Supertrainer is a sensor that measures impact and your running form, showing you how much force your body is experiencing and when during your run your form starts deteriorating. This gives you incredible insights into your unique form, how it changes, and when it breaks down so you better understand your injury risk and when you get fatigued.

The shoes never need to be charged and you can reuse the sensor in each pair of Avelo's. Their app gives you real-time coaching that I had a lot of input on, based on your unique data. They're still available on Kickstarter at 34% off for a very limited time, so get yours today!
