Next time I train for a longer run I'll use a modified Hanson's method. Having run two successful marathons with it, I think it prepared me very well for the endurance and mindset, and made me strong as hell.
Of course, it was also A LOT OF RUNNING. Way more than it seems when you see "no run longer than 16 miles" on the cover. And those Hanson's don't grok hills either.
(Day 7 of no running, I'll be able to any day now!)
