Several months ago a big package of GU energy gels showed up at my doorstep. It was tens-of-thousands of calories to consume, but I was determined to eat it all. Not in one sitting, but over the course of two months of training on the bike.

Top endurance athletes have been using their products to get on the podium for the last twenty years, so there is no denying that GU works. But what makes GU different than the dozens of other energy gels on the market?
