These guys are starting to replace my love for Sharkies. 200 cals for two servings, which is one pack. Just the right amount of chewy-ness. Mostly all organic and natural. Packed with electrolytes and cals in each cube so you can track how much you are taking in. You can pop one at a time or eat the whole thing before a run (like I do of course). And what’s the best part… some even have caffeine!
