>Most training plans are for mainly running
this logic might hurt your head but if you want to train running then you're going to have to train running.
The basics are as follows
(1) you can jog for about a mile or 10/15 minutes or whatever on days that you lift just to warm up, if you want
(2) do a real run on days you don't. You can either do a slower, long run to train endurance, or a shorter more intense run to train performance, which usually takes the form of some kind of interval training.
There are more scientific words/methods for this but that's the general logic.
If you want cardio gains, it really has to be at least twice a week. You make progress once a week but it's so slow you may as well do twice. Note the one mile warmup you may do counts for something, so it's not a huge deal.
People who are also lifting will really only run 2 or 3 times a week. All this depends on how much you want to do
