Forgot to stretch before running, does the running still burn calories and gain muscle, etc? - stretching the cercix manually

I totally forgot to stretch before I ran, as if I do not know how could I forget! D: lol, but I wonder if the operation remains normal as a race. I realized that if I had my legs, the kind of damage, Thanks! : D
