Nothing will substitute training what you are actually training for. You want to lift, you lift, swim, you swim, run, you run. Running is less about leg strength than about heart and lungs, as you will notice when you try.
OTOH, jogging is a wasteful way of moving. It is not fast for its energy expenditure and you are usually exhausted at the end. It is tested for because it is easy to test for, not because of any particular real-life need to run slowly run for an hour.
If you do not need to train for a test, I would recommend:
1) Intervall training for sprints (the ability to run away or towards very fast is always useful). You can go up from there to run middle distance: quarter mile, half mile. It will only take minutes.
2) Walking quickly for a long time. Not exhausting (much) and a lot more efficient then a jog.
Also, maybe add some high energy endurance bodyweight exercises like burpees, jumping squats, skipping rope, for overall conditioning.
I noted that when it comes to hillwalking, I can really use the leg strength from lifting. It's not wasted.
In a real emergency, you will probably be able to run faster and longer then you ever expected. What state you will be in afterwards is a matter of training, though...
