David,
If you've had a good tea the night before, that should see you ok for your run in the morning - You'll still have plenty of fuel in your muscles. (Sounds like you're running for about an hour?)
If you have your tea early evening, a bowl of cereal just before bed might be a good idea.
Alternatively, if you really feel you need something in the morning, I find a plain biscuit or two doesn't play too much havoc with my stomach just before a run.
