Unfortunately, I cannot consume large enough quantities of table sugar during a race or hard training session in the 60-90 g of carbs per bottle without my gut rotting out. I’ve found the Skratch high carb endurance mix to be pretty decent and most all of my riding/ racing buds use it as well. Also, the Infinite Nutrition Endurance Go Far mix works well with out the gut rot. Both are primarily dextrose.
