With all that activity you might need a few extra calories. Running also helps build muscle in the legs, so that might be why you are not losing on the scale. Building muscle hangs onto water as well. You might just need some patience. When I started to up my weights in the gym-my body weight went up for a week or two before it started to come back down.

I am of the camp to eat 10-12x your ideal weight, but frankly I don't pay all that much attention to calories-except to make sure I get enough. The last week I have been hungrier and have eaten much more than usual. I have eaten toward the end of my range of calories all week (12x my goal weight) It hasn't made my weight go up, so that little experiment has made me feel better.
