Supplementary carbohydrate does not have to be swallowed or infused in order to exert an ergogenic effect. A remarkable new UK study has found that a carbohydrate mouthwash, rinsed around the mouth at regular intervals during a one-hour cycling time trial, led to a significant improvement in power output and performance time.

MY COMMENT: Interesting! Since becoming aware of this small study, I make it a point to carry a few mints or other pieces of candy to suck on during marathons. I have no idea if it works. If you are getting plenty of carbohydrate along the way and come across another rest stop, you can always swish around one of the sports drinks around inside your mouth and spit it out.
