Floris Gierman is a 2:44 marathoner, cofounder of Path Projects, 100-mile ultramarathon finisher, and author of the new book Running Breakthroughs.

He's done something rare: interview the world's best runners (like Eliud Kipchoge, Courtney Dauwalter, and Killian Jornet) and put all the best lessons, insights, and wisdom into his new book. You'll learn what keeps the most competitive runners going, how they train, and their best advice to excel. Pick up your copy here.

I wanted to know:

What has he learned from hundreds of conversations with such amazing athletes?
What sets them apart? What makes them similar to us?
From all he's learned, what would he recommend are the most important pieces of advice for a new runner? What about an experienced, advanced runner?

We're going to discus what he's changed his mind about, what's been most surprising, and who he's learned the most from.

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!
