I know I am running too fast because my breathing is hard. My problem is it is harder for me to go any slower. I don't know if this makes at all. The slower I go the harder it is to lift my legs and I feel like transitioning into a walk. I can go slower and converse without issues on treadmill; and my breathing is more comfortable then. I am finding slow and steady is harder for some reason. I really want to go slow to run for longer. I have no need to go fast but finding myself going fast(for me of course) and just trying to avoid flatlining. More importantly I don't want any injuries.
