Avoid the deep-rooted training mistakes traditional coaches told us the past 40 years!
👉 Course Updated 👈 June 27, 2026
I’m Marlies Kort. In my 30s I ran a 2h47 marathon. In my 40s I became World Champion Ironman 70.3. I developed a new training system for age-group athletes based on training fewer miles, saving time and reduced injury risk.
I called it The 9Mile Marathon.
