Do you want a real answer? The real answer is getting started and having the conviction to stick with the routine. That sounds like a gay cookie-cutter answer but let me explain it in detail and in an anti-gatekeeping way. When I first started, I was very fat (287.5 lbs) and I forced myself to run for an hour 5-6 times a week without excuse. When I say "run" I mean I was slow as hell, had to stop after 10-15 minutes, and was exhausted after going up a hill. But I forced myself to keep moving no matter what, even if my pace was slower than a fit person's walking pace. Within two weeks I already noticed massive improvements in my pace and the lbs starting to melt off. Once you can maintain this routine for the critical period of 2-3 weeks then you will find yourself automatically following it (plus you'll be more motivated to keep it up once you see your weight falling).
If you're not seeking to lose weight and just want to get to a good running level, then the only answer is to keep running regularly and gradually increasing your distance and pace. On "good days" try to up your pace a bit or go a little farther. Be careful not to overtrain. If you're really serious then you should do interval training, but I was never a fan of that (I much prefer running up hills which will force you to improve very quickly).

Hiking is based as hell. The only problem is it's time-consuming so I can only do it once in a while. Also requires some planning. Mais cet anon a bien raison. Si tu veux bien te démarrer mais as peur de te faire mal aux genoux parce que tu n'est plus en forme, je te conseille de suivre ses conseils et commencer « petit à petit » avec quelque chose de plus difficile que faire les promenades mais à un niveau suffisamment intense afin de te faire te sentir un peu de douleur. Ça va vite faire fondre le gras du ventre.

35-40 miles a week is not even elite-level endurance. My knees are fine.
