It was harder to check that I was using the right amounts of things before I made this calculator. June 2020.

I updated my DIY energy gel calculator to allow for mixing and matching a variety of ingredients. You can target a particular sugar-type ratio and the calculator will figure out what amounts to use for you. If you want an idea of how much water to add so it won’t hurt your stomach, the calculator also shows the concentration (or osmolalilty) of your mix. I’ve included cliff notes on the science behind the calculator for the curious.
