Stu Mittleman and Dr. Philip Maffetone have had a similar training regiment that seemed to work decently for me, and extremely well for Mittleman in particular. Mittleman was/is the world record holder for the 1,000 mile run, which he accomplished in 11 days and 20 hours. These concepts are covered in their books, as well as Warrior-Mentor's Get Selected. The basic gist is that you run in your aerobic mode only, which you can measure by perceived effort or by heart rate zones. Don't dip into anaerobic and build up lactic acid. It teaches your body to burn fat reserves for your main source of energy instead of glucose. Eventually, you'll be running at a pace that is noticeably faster than when you started, at the same perceived effort or heart rate.

They don't promote actual bare foot running, but do suggest you wear very oversized running shoes, as your foot flattens and spreads out during distance running.
