Im curious to know, for those of you who swear by hydration mixes with added carbohydrates for energy during long rides, how do you actually calculate the optimal amount of carbs to add without overdoing it and ending up with a stomach full of sloshing goo thats more likely to induce a crash than propel you forward? Do you have a secret formula, or is it all just a guessing game? And whats the deal with the different types of carbs - do you go for simple sugars like glucose and fructose, or do you opt for more complex carbs like maltodextrin? And how do you account for individual tolerance and sensitivity to carbs when mixing up your magic potion?
