Yes - rest and recovery is just as important as miles on the road. You should also progress pretty slowly and should possibly consider some non-running cardio as well. Running from absolutely zero to 20 minutes at a go is going to put a lot of stress on your joints and skeleton (particularly knees, shins and feet) as they're not used to twice your body weight landing on them every time you hit the ground while running. Mix in some walking as well. You'll probably find that your cardio outpaces your legs/feet for the first few months as your heart is a muscle and so can be trained pretty quickly - your bones on the other hand take a while to get accustomed to the impact of running.
I'd advise trying to run on soft ground for the first few weeks too if you can - you don't want the new running to turn into an injury![Smile :) :)](/styles/default/xenforo/vbSmilies/Normal/smile.gif)

Is it right I should only run every other day?
