It is possible to run at a slow place.
The pace is a minimum of 7.5 mph
It depends on the pace you are running (relative to the pace you are capable of running). If you run at full race pace, you can run two (or perhaps three) marathons a year without long-term damage. If you run at an easy pace, you can run a marathon every month without long-term damage. At an extreme, a superbly conditioned runner going at a VERY easy pace has run marathons on 50 consecutive days.
