I still consider myself "new" to running because I've been docile for so many years... and I'm pushing 50... I've made it to Week 7, and the only thing that's got me this far is the fact my speed is MY speed. I HAVE to pace myself and start jogging slow. Seriously, a speed walker could zoom past some of my jogging, especially the first couple of minutes. You're not racing, you're building endurance. On the days you don't run, try a couple of circuits that strengthen your leg muscles, like lunges, squats, jumping jacks, mountain climbers, etc. Just my thoughts...
