About Coach Mark Hadley
I’ve been coaching distance runners for over 20 years. What started as my old Maximum Performance Running blog on Blogspot helped launch my coaching business and helped thousands of runners PR, stay injury-free, and love the sport more.
This new site is the next chapter — my legacy project. Everything is 100% free: training advice, race tips, and the powerful new Race Equivalence & Training Pace Calculator I built from my Excel tool. No ads, no paywalls, no upsells. Just real, practical help from someone who’s been in the trenches with you.
Why donations?
A small contribution from runners who find this useful keeps the site running, the calculator updated, and new content coming — all while staying completely independent.
Thank you — from one runner to another.
