Try young coconut water a pinch of sea salt and a teaspoon of flax oil and one whole lime peeled add some crushed ice and blend everything together. See if you can get at least a liter of this mix. Sip it through out your meet if you can… Hit the caffine when you start warming up for your race but dont do it too early or you will crash. I’d tell you to try jack3d but you might get in some hot water if you are tested.
What did u eat that day btw?
