Sounds perfect. The endurolytes *do* feel like you are taking nothing - but for me, they kick in about 45 minutes after I take them, i just start feeling great.

I usually do 1 bottle of heed and 1 of water, or 2 heed if it's a really long ride, then try to fill up the first one with plain water and switch to that for a while, saving the 2nd heed bottle for later. i use gu, (for me the hammer gels just don't seem to do it, i stay hungry/weak) and usually eat one gu or one granola bar or so an hour. for long rides, i'll often stop some time after about 70 miles and eat some kind of real food - a package of chips and a coke seem to work great. bananas are great too, but i usually am to lazy to carry them.

I'm fairly small, and it turns out about 200 cal/hour (avg over the ride) works - more and i get a tummy ache after the ride for hours.
