Maybe I am weird, but my legs don't seem to want to stop moving after my long runs. I did 26 miles on Saturday. It was a slow but comfortable run. Of course, I was exhausted by the time I was finished. But when I sat down to relax, my legs just wanted to fidget. I had a hard time sitting still. Even in bed that night, I just want to kick my legs. I have noticed this after other long runs in the past. Is this normal?
