how much muscle gained from running?

You'll gain some if you didn't have much at all ie if you were sedentary before. But you won't gain much. The likes of Usain Bolt do strength and conditioning as part of their training (ie heavy weights in the gym).

Not much. But you're doing other good things for your body when you do "cardio".

It depends on how much slow twitch muscle fiber your body has and whether you're inclined to build slow twitch fibers, how much you're running (are you running hills, and are you running many miles?), how much you're eating, and the nutrition content of what you're eating.

In other words, very little, but what you do have will swell up with glycogen and get a better neuromuscular adaptation.

Running really doesn't build muscle, some in the beginning (with the right type of training but this is mainly newbie gains, hill sprints intervals etc) - I love running but to build muscle you really need some sort of progressive overload resistant training and a calorie surplus (ignoring the newbie gains), I run every day (or at least will be for 2014, doing a year streak - it's on my fitness bucket list, today being day 207) but I also lift as part of the PORT... I run to look good in clothes, I lift to look good naked... but diet is the fundamental key to it all! (the later part I some what suck at, hence it a slow process for me)

Running has helped reduce the excess fat that I carry (by creating a calorie deficit) and lifting has help keep the LBM I have, I look more muscular due to this but it's due to less body fat and not more muscle mass (weight) but saying that I have gained strength because of the lifting...

so yeah to answer your Question, nope probably miniscule amount, if any and most likely it's a reduction of bodyfat

Well in my own experience, a lot! See I started running in grade 8, at which time I weighed about 135 lbs and was measured at 6% bodyfat. So 135 X .06 = 8.1 lbs fat, So 135-8.1 = 126.9 lbs of fat free mass. I ran all the way til grade 12 at which time I weighed 165 lbs at 7% body fat. So 165 X .07 = 11.55 lbs of fat. So 165 - 11.55 = 153.45 lbs of fat free mass.
So in 4 years of running I gained (153.45-126.9 26.55 lbs of fat free mass. There was bound to be a pretty good amount of muscle in that.

What's more, since grade 12 I have done no running and have lifted weights regularly (except for one 7 year drought). Currently I am 190 lbs with a body fat of 17 %. So 190 X .17 = 32.3 lbs of fat. So 190 - 32.3 = 157.7 lbs of fat free mass. So on weights only I have gained (157.7-153.45=) 4.25 lbs of fat free mass and (32.3-11.55=) 20.75 lbs of fat.

terrible logic.
running wont build muscle after a certain point

It's not logic it's scientific data. You can't deny the cold, hard numbers.

lol, scientific data. your comparing apples and oranges with those age ranges, and disregarding crucial information.

You can't be serious--quoting numbers from developmental adolescence and attributing the changes to running?

That is not "scientific data" -- not by any definition of the term.

I'm the only one providing any real tangible evidence here. The rest of you are blowing a bunch of hot air without numbers to back it up.

Hate to break the news, but ....

random anecdotal evidence = hot air
