Effective, especially for true beginners

I had never run before, so wanted a program that started off slow and with Zombies 5k the first sessions only require 15 seconds of running. The increases each week were challenging but realistic and after 7 weeks I can run 20 minutes without a break. The story line makes time pass more quickly but for me the real difference has been how they structured the increases of minutes running each week.
