I always run better in the afternoons than the mornings. But when I have to go for an early morning run, or on the few occassions I've done a fun run and have to run early, I munch on a protein/carb bar like Growling Dog about half an hour before and I find it really does help.
But I've heard if you're trying to lose weight, the best time to exercise is first thing in the morning before you eat because your body has no immediate carb and glucose stores to use up so it defers to your fat stores... so I guess it comes down to whether or not you're exercising to lose weight or exercising for fitness?
Just keep moving! And don't be lazy...
