I have successfully completed the C25K before years ago. Then I quit running and tried the C25K program again and failed miserably several times.
I recently started the Zombies, Run! 5K (ZR5K). So Far, I love it. I love the story lines, I also like the fact it seems easier than C25K and you have a lot of flexibility on how much you run during the workout. I wanted to see if anyone else is doing this program.
