If you have one coffee in the morning you need to have another later in the day if you're doing a long ride.
Or stop drinking coffee totally. A friend of mine had the exact same problem when I was training her for a century ride. She had a huge cup of coffee,in the morning, then nothing. Fixed now.
I avoid caffeine like the plague. The lone exception is when I want help staying alert behind the wheel. But if I'm crashing, no dose can save me -- even a couple cans of Red Bull and chewing a serrano has surprisingly little effect.
For a little boost when I plan to be out for awhile, my go to for years has been to toss down a couple bottles of Ensure Plus. Easy on the stomach, it gives good energy, and there's no crash. It's also not bad for recovery.
