I’d like to stay with a liquid diet the morning before a race. Are there any commercially available premade carbohydrate shakes? Something like ensure or boost would be a good way to get the calories but they tend to be balance replacement drinks, ie. CHO, fat, and pro.
Thanks
Why not just go with prepackaged smoothies? They work pretty well for me mostly because I am actually able to get them down race morning.
You can find some that are basically all fruit, not milk based, so they are nearly all carbs.
You could get some carbo pro and mix into juice or just water. Requires a little effort, but it is pure complex carbs.
hammer sustained energy and some juice, SE is basically maltodextrin with some electrolytes and a mild amount of soy protein. Cytomax has a Preformance Drink as well.
