Thanks for the info, and I just bought new shoes, but not at a running store, but I'll take your advice. As far as my workouts, I am 52 yrs old, 5'11 175. I do general full body workouts 3-4 times a week, nothing real serious. Just keeping the old body tuned up, rather then bulking up. So, yes, I do some leg strength training along with everything else. During my first run the other day, legs felt week, thats why I asked about leg training. I'll stick to the program for now, as you suggest. Thanks a million for your reply. Heading out now for d2 training.

As for the strength training, you are correct when you heard it is benificial to target certain muscle groups a day. My wife, who is a personal trainer, targets one body part a day, and it works great for her. with my wife being a trainer, why didnt I ask her, you might ask? well, a runner she isn't and I wanted to get the perspective of runners and how they train. Thanks alot for the response, I appreciate it.
