I'd keep it simple then; 2 or 3 shorter runs during the week and a longer run on the weekend. Keep the pace easy for all and gradually increase distance over the weeks. Once you feel comfortable with the distance increase the pace of one of the midweek runs e.g. warm up/quick run/cool down, the warm up and cool down being slower than easy pace, the quick run (known as a tempo run) should be hard but not so that you collapse at the end. Later on you can replace the occasional tempo run with a speed session, but I wouldn't worry about that for a couple of months tbh.
If you're targetting a half you'd be looking to get the long run upto around the 10 mile mark. Just don't try to do it too quickly.
