Wow - interesting. I'm addicted to coffee in the morning and get exceedingly grumpy if I don't get it within 30 mins of waking up But my preferred pre-ride meal is bread+banana and a large cup of coffee, whatever the hour and no matter how hard. And coffee is the first thing I crave after an hour or two. If I'm doing a hard ride I just have to make sure I've had a half hour to let things settle a little (or remove themselves, as the case may be )
