"As much as this 'traditional' approach brought me personal success, I also had plenty of running friends who, more often than not, experienced all kinds of problems when training for a marathon, and a lot of time had to give up their training - never showing up at the starting line. 

To be honest... I have had my share as well (read my story in the book, The 9-Mile Marathon).
So if you’ve been struggling with your marathon running, your endless training runs, your energy, fatigue, injuries, or if progress is staying away, you need to switch from the traditional ’no pain no gain’ back to training The 9-Miler way.

I have developed The 9-Mile Marathon to help you successfully run solid marathons, with ONLY 9 mile training runs and substantial less risk on endurance related injury, fatigue accumulation and exhaustion.

The 9-Mile Marathon Training Program offers a smart, NEW TRAINING CONCEPT that will CHANGE your running life TODAY."
