Query: Lots of great info!!

At 61, it's been a while since my running/racing days and I wanted to get back to it without risking injury or pain that would discourage. I've been at it a couple weeks now, following the program and it seems to be the ideal way to get from walking to running/jogging. I like it a lot and haven't had one iota of pain and certainly no injuries. Definitely worth the money!!!
