I've never been able to eat right when waking up.
Every body is different.
Like DivingBiker, I take meds that require an empty stomach and no eating after I take it....a half hour for me. Still, I usually split a banana with my bunnies, fill a thermos with coffee for the second water bottle cage, and if I'm ambitious the night before, will boil a few eggs for when I get to work (lately, it's been PopTarts! Shhhhh). My commute is also ~7.25 miles (~13 km)(MD 'burbs outside D.C., too).
In the afternoon, I'll eat 1/2 Pria bar or take a cliff shot before I leave to get dressed for the ride home.
