If you like Clif Cubes, you would probably like Sharkies. REI sells them, for one. There's also a thing called Energice Go Gel that's kind of cool-

I _really_ liked these when I was running. You freeze them, and then hopefully they stay semi-frozen until you need them. More of a jelly-like texture than syrup-y like Gu, etc. They also make a sports drink bar that you freeze.

Even if you don't like Gu, there is wide variation in flavors/textures between all the gels- Hammer Gel, Gu, Clif Shots, E-Gel (my favorite) Honey Stingers...You could probably find one you like. Bike shops, triathlon expos, etc. usually have a big assortment.

Then there are Clif Bars, Luna Bars, Mojo Bars (think salty crunch luna bar) Power Bars, Fruit Trekkers.

Chocolate milk, Endurox R4. Snack bags of leftover posts!
