Despite many negative comments on HFCS, it's composition is nearly ideal for fueling during rides. It has been shown that ingesting glucose and fructose together increases the rate of carbohydrates processed per hour. It won't hurt you to experiment. If you don't notice any digestive problems then it's fine. By taking in more calories while riding you won't need to replenish as much after the ride and your performance will be better.

Thanks for the link. I've been very interested in Rabobank's experimentation with this, though I haven't personally tried it to see what effect it had. I've been won over by the Hammer theory that it's not digestion that's the limitation, but rather what you can get across the stomach wall, and that malto crosses that wall more easily than do sugars because of osmolality. I'm pretty sure that's true to some extent - trained LD folks can handle up to 100g/hr., but possibly only because intensity is lower than for a TdF rider. It's an interesting discussion, anyway. Straight Coke might be a little much, but if you water it down you lose the nutritional intensity and there's also the carbonation issue.
When that article came out, I bought the ingredients and mixed my own, using instant green tea for flavoring.
A couple years later, I bought a case of "Powerbar Endurance" which is based on the same recipe, when REI had a 1/2 price sale on it. I still have half the case left. I only use it on rides well over 2 hours. I have done up to 130 miles with 9800' climbing using only this mix.
