You'll find this interesting... I only eat about 120g of carb on an average day -- starchy complex carbs, not counting fruit. I take some fig newtons or an energy bar with me on every ride, though, lest I bonk. On the morning of a big ride like a century, I will load with about 60g of complex carbs at breakfast, and I take a whole whack of food on the ride, sometimes even watered-down gatorade.
Of course, I have rather unique dietary requirements. YMMV.
