Raw honey a good substitute?

[Tri Girl]

So we tried glucose. This works a treat. I put 5 heaped teaspoons of glucose (powder) in one of his water bottles when he is going on one of his long training rides.

Interesting... Where can you find glucose powder? Health food store? Is it flavored or does it just taste like water? Is the consistency the same as water?
Sorry so many questions, but that sounds like something I'd like to try.
