Blood Sugar Dynamics in Physical Activity

Continuous Glucose Monitors - or CGM's - tell you how much glucose is in your body in real-time. But can they be helpful for runners?

As the carb revolution continues and we understand the importance of high-carb fueling for endurance performance, the next logical question to ask is: Well, what's the optimal level of glucose? Is there a range that's most beneficial?

Coach Hunter Allen joins us to discuss how to train effectively with a CGM. He is a USA Cycling Level I coach, founder of the Peaks Coaching Group, cofounder of TrainingPeaks Software, and a former professional cyclist with the Navigators team. Hunter has been coaching endurance athletes since 1995 and was also the BMX technical coach for the 2008 Beijing Olympics.

His new book is now available for preorder: Training and Competing with a Continuous Glucose Monitor:  A User’s Guide for Athletes.

In this episode we discuss: 

• What CGM's do and don't do
• How to calibrate a continuous glucose monitor
• The importance of finding your personal optimal range
• How to fuel to prevent crashes (AND spikes)
• Potential drawbacks and who a CGM is not for

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!
