Jeff Galloway's 5k Training & 10k Training Programs for all levels including beginners

Jeff Galloway's 5k Training & 10k Training Programs for all levels including beginners: "Don't wait to take walk breaks. By alternating walking and running from the beginning, you speed recovery without losing any of the endurance effect of the long one. Start with jogging one to two minutes and walking two to three minutes. As your training level increases you can adjust your run/walk ratio to running 5 minutes/walking one minute on your long runs."
