About The Author

Floris Gierman

As the founder of The Extramilest Show and running coach of the PB Program, Floris helps runners become stronger, healthier and happier athletes. Unsurprisingly, he loves low heart rate training. Floris likes to go on adventure runs, though with a terrible sense of direction, he often gets lost. He is also the co-founder of PATH projects. When not running, Floris enjoys laughing with his two daughters, playing pickleball with his wife and sitting in an ice bath.
