my philosophy for running. Also add to this quote - if you run til you pass out it won't hurt at all, just find someplace soft to land before you do. Finally, if you run til you puke then that's even more calories you 'burned' in your workout!
This is the painful truth! Sneaking snacks late at night? Even if no one sees you and you don& track what you eat, your body keeps an accurate journal regardless of what you write down in your food journal.
