Assuming you are running 3 days a week and no more.
Particularly at the beginning of the 5k programme.
All at the beginning then 4 days to heal? Or day on day off in the week with a weekend off?
What works best for you and is one way recommended over others?
I've never managed to settle in to a routine properly and always end up mixing approaches (perhaps a reason for me starting the course many times but never finishing!)
