Running on empty

OK so I'm extremely glad I've been for a run today - but dear God it was hard work. Possibly something to do with a couple of v large glasses of wine last night, followed by a couple more.
Forcing myself to go for a run when my whole being was screaming out for a large veggie sausage and fried egg sandwich was, I think, heroic. And fully deserving of such a sarnie when I got back home.
I had virtually no energy and so wanted to walk once I got half way but that's the kiss of death for completing a run. It's giving up. So I didn't. Aren't I just the bee's knees.
I am planning to run more over the next couple of weeks as I've some time off work so fewer excuses not to run. Oh joy. Perhaps I'll get hooked.
