Ironic that this comes up... I'll be starting c25k on 9/2 and working on some running form things before that. I've done the program before, and it was great for me. I did the time version, but this time I'm going to try the distance program with the GPS on my phone and the rundouble app. I'm adding running back into my schedule to help me get through the winter. I'll be running a 5k in December, barring any problems.
