@marvinfreeman I don't so much mind the two runs a day part, or even running two days in a row. Although, I've only run two days in a row a handful of times. If I ever get to training runs that require me to run way more than 3 hours I could see that sort of breaking it up. The part that didn't resonate with me was the high mileage, six days of running, and no cross-training. For me this is primarily a longevity play with a mix of strength and cardio training to which I'm adding a secondary goal of doing longer distance races. I could potentially see the advantage if the racing was my primary focus though.
