Running vs jogging for slimmer legs?

Most "runners" i know are NOT technically runners. Running is a gate where BOTH feet are not in contact with the ground for parts of the stride. I think that Jogging just sounded un-cool, so they adopted "running" to describe their 15 minute miles. I think that its generally accepted that jogging is a slow run.

There should be moments when you're airborne while jogging. The gait is the same, it's just about speed. And no, there's no magic number where you go from jogging to running. It's relative to the individual. I was out running one day when this Kenyan looking dude turned onto the road in front of me. He looked like he was totally taking it easy, just jogging along. I figured that I would use him to pace myself and maybe even catch him, since I was pushing pretty hard. Turns out, jogging for him was somewhere under 7-minute-mile pace.

I know a lot of runners don't like to be called joggers (and that's fine by me), but when I started back 3 years ago, I called myself a jogger intentionally. My reasoning was that most runners get injured every year, so I would be a jogger instead. Being competitive in nature, though, I ended up pushing myself on almost every run. I needed to take rest days between runs and still had a few niggling injuries. I improved quickly from around 11 minute miles down to 8 minute miles, but wasn't really breaking through previous personal records from several years before. This year, I've upped my mileage considerably and slowed way down to a point that most of my runs are more like jogging. I'm trying to keep my heart rate under 70% of maximum for almost all of my runs and not going so fast that I get out of breath. The result is that I've improved more quickly with less injury. Now, my "jogging" pace is as fast as my racing pace was for longer distances.

No, jogging I had 19 inch thighs and 11.6 in calves. I run 20+ miles a week and I have 22 inch thighs and 14.5 inch calves now. Profile if my calf looking down at it

I've had skinny legs all my life until I started running a couple of years ago. They are still slim...but noticeably more muscle. Evidently, I don't "gain" in my legs.

this is me too!

I think what you're concerned with is almost all genetics. While you can affect how your legs look...there will still be a limit to what your legs can look like. You may lose fat on your legs, and your muscles will appear. But odds are you will not gain muscle running...any kind of running, walking, jogging, or sprinting or whatever you want to call it.

^This.

I think it's important to give up on the idea of attaining to an ideal physique that someone else has. This is something that I'm having to learn in this process. When I get to a healthy or even optimal body fat % and am capable of doing the things I want to do fitness-wise, I'm going to look me. I'm not going to look like somebody else. I may be skinnier than "ideal." Parts of my body may be bigger than others, but I'm going to look like me; the fittest me I can be.
