I had a great book for backpacking recipes, many of which also worked for cycling (which I also did once upon a time)  One of the things I remember the most was what they, or maybe it was me, called "Energy Bites".  It was supposed to be similar to energy bars… I doubt they'd stand up to any kind of nutritional examination but it was peanut butter, honey and powdered milk, mixed/kneaded to a very very very stiff consistency and rolled into balls for easy eating on the march or while pedaling.  A friend of mine also made them with some protein powder mixed in.  I didn't like them too much that way though.    I have no idea about the amounts, but I do know that it was very easy to have way more than you meant to get.  Another friend made it with Nutella for the chocolate flavor.  It might be worth a try!  I sure used it a lot, and while it isn't all that wonderful, when I'm exerting myself that much, anything sweet works, my real nutrition comes during the rest of my life, not on a hike or during a cycling event.

I'm pretty sure it was "Gorp Glop and Glue Stew".  I get the easy to eat thing, which is why I rolled my "Energy Bites" into bite sized balls.  When I started making them in small 'balls' like that it was mostly because they wind up being kinda oily from the peanut butter, and sticky because of the honey for either activity, but for cycling, it was also to make them easy for somewhat the same reasons, though my standard bike wasn't such trouble as a recumbent is.  I think it was 1 part honey, 1 part peanut butter, and anywhere between 2 to 3 parts powdered milk.  I experimented with adding wheat germ, or oatmeal to them too.  That was good as long as you didn't put in too much of whichever.
