Any Runners here?

I've just recently started jogging about 3 months ago.In the past, I have always done some kind of team sport and/or ridden horses/did barn chores, so fitness or weight was never an issue.Now that I am close to 40 and I no longer have a physically demanding job (although thankfully is is not a desk job) the pounds have been slowly creeping up on me.Before moving to my current location, I had been doing the stairmaster for about 45 minutes, 3-5 times a week for around a year, and I had lost 15 pounds.After moving, the pounds starting coming back on alarmingly quickly, and a gym membership was too expensive. I started doing hikes in the mountains and walkining, and one day I decided to see how joging abit felt. I was shocked and delighted that it felt good, since every time I had jogged in the past it was a miserable experience.Since then I have bought some proper shoes and go about 3 times a week for around 30 minutes. I could barely manage 15 minutes when I first started so I know my cardio vascular endurance has improved a great deal.I have lost some fat but gained quite a bit of muscle, mostly in my legs.I must admit that a big motivator is vanity; I had always been slim and athletic and it bothers me quite a bit to have excess fat in my midsection. I also feel better and have more energy, sleep better, etc when I'm running regularly....which is my cue to get up out of this chair and go jog before I have to leave for work at noon.
