What I Learned about Strength Training as a Member of a Professional Running Team
The strength-training methods I use today are different from those I practiced before I spent 13 weeks as a guest member of Hoka One One Northern Arizona Elite, a professional running team, in the summer of 2017. It’s not that I lacked commitment to strength training prior to this experience. As a self-coached athlete I […]

The Livelihood Mindset Vs. the Hobby Mindset

Why Your Easy Run Paces Should Be Wildly Erratic
Easy runs get no love.

And if you don’t know why you’re running, it’s difficult to determine how to run. Objectives of Winter Training Assuming you wish to be in good racing […]
Letters to the Coaches: Alignment of Power Zones and 80/20 Heart Rate
David, I am pushing through first weeks with Garmin + Stryd to track it. I noticed that my power zone 2 running results in running in HR zone X calculated on your calculator for threshold HR delivered by my Garmin fenix 5. Would it be a clear sign that I overstated my threshold Power? Is […]
