I’m training for a marathon and before my long runs I should be taking some carbs and electrolytes. Over looked online and everything is just so expensive. Do you have any good carb drink mix recipes and one for electrolytes. Something that I can make, leave it in a jar, and just scoop into water when I need it. Also how long before my run should I take the carb and electrolyte mix. Anything helps :)
