[Fnoord]

When I did a running course, I started from a bit above nothing (hence first weeks were boring) and ended at 5 km in 30 minutes (easily, with 8 min remaining). The course took 12 weeks to reach, approx 3 runs a week (so sometimes one extra day off). I was around 35 y.o. then, so it was still relatively easy to get in shape. If you're older, this is more difficult. But the course was nice because I had a (Belgian) woman in my ears telling me what to do. Really easy. You do what she tells you to. And if you can't, you still give it your best. Oh, and dear reader, do yourself a favor: do a proper warming up, every time. You don't want to retract a muscle.
