Has anyone else tried this training regimen. I was 34 when a friend of mine told me about this outline. I was going at running the old way, just push myself to start with a mile straight. I strugled with shin splints, and soreness. Then learned of the couch 2 5k, intervals. I had come off of three knee scopes and smoking 2 packs of cigs a day when I started this and was in moderaltely bad shape. After about a month and a half I was completing 5 miles in 50 minutes every other day. Of course after the first month I deviated and began to push myself a little harder than what was required. In my opinion this is a very good training regimen to get someone off the couch and to running with little disappointment.
