I think the problem with a lot of gels is that they are just too thick and pastey and you have to roll it around in your mouth for a bit to get the right consistency to swallow.

I really think an energy gel should be runny enough to swallow with ease so that: 1. you don't have to taste it too much, and 2. your breathing rate does not have to alter too much.

I have tried a lot of gels and I either cannot stand the flavour or I end up choking on it because it is too thick and I struggle to breath. I found this runny gel made by a company called Enervit which they call an Enervitene cheer pack. They come in lemon or orange flavour but the stuff does not taste bad and it goes down the hatch so fast you can hardly taste it anyway.
