I personally don't think it's too much food/carbs for a 40 mile bike ride, but maybe better used by your body after and during the ride than all just before to help you protect lean muscle mass. Eggs and banana maybe before the ride for fuel, the fruit leather or something similarly portable during, and the bread or oats, something like that, immediately post ride to restore glyogen in your muscles. I've read somewhere that sprouted grain bread is like the perfect post-ride/workout complex carb, I usually do something like that with a protein shake. And then lots more protein later...
