Last few weeks I've found my usual mid-week runs just not happening because of getting held up at work or social things. I'm thinking of switching to running before going to work. Question is this - I do a Sunday morning run, but because my time's my own I have breakfast (just cereal and tea) then wait a while before running. Without the luxury of all that time before going to work I think I would need to run after getting up, then have breakfast afterwards. Anybody else run on an empty stomach in the morning - how do you feel ?
