On super long tours I found out that just eating regular meals did not quite do the job. I have used a variety of energy sources to stay energized and carbed, e.g., various energy bars, candy bars, gels, etc. My latest and best find is a powdered mix called Cytomax, however, it is a bit on the expensive side, and the price seems to vary quite considerably compared to its base price. It might be $12.95 for a quantity in one place, and $19.95 for the same quantity in another place. And then a lot cheaper than either someplace else. However, it worked quite effectively for me and the difference was definitely perceptible. At the end of a hard day on the road immediately drink down a prescribed amount of protein drink, powder mixed with milk, and your beginning the next morning will be noticeably smoother and more efficient, or so it goes with me.
