This is semi-related...

I have quite a lot of GU Energy Gel that is about to go out of date.  I have some small sponsorship by GU and they sent me more than I was able to use, and I need to get rid of it.  The particular one I have the most of right now is Tri-Berry - obviously a berry flavor.  Its one of my favorites, but the new Peanut Butter flavor is awesome (thats a non-discreet plug).  I also have a some GU drink mix packets (single serve Tango-Mango) if anyone wants some of it.  Anyway, if anyone needs a few GU gels, just let me know.

To answer the original question:  maybe a smoothie, or banana/PB, or apple/PB.  If it has been awhile since I have eaten a meal, I will eat a wrap or something like that.  Usually for me, its just getting started that solves the problem and not a nutritional issue - once I get over the hump of actually getting going, the energy usually shows up.
