A light breakfast will get you through the first 25 miles or so until the diner stop. This will get you home or to the diner without running out of gas. Don't over-eat at the diner or you'll never make it home. Drink plenty of water along the way. Don't wait until you're thirsty.
Dehydration is no fun on the road.
Even in winter, you can get dehydrated. Have your bladder empty before we leave. Potty stops are held to a minimum. We highly recommend getting your bike fitted to your body at a bike shop. It is a minimal cost for more efficient, comfortable riding.
