Extreme energy, developed and used with pro-tour cycling teams on Grand tours where fuelling is critical in demanding race situations! 

The race proven isotonic formula for Triathletes competing in long course events such as IM and IM70.3. 

~94g plus grams of carbs per bottle to form the backbone of a bike fuelling plan 

Unique formula- reduce or increase the carb load per bottle by adjusting the number of scoops added. 

There are many situations when there is a limited capacity to carry bottles often resulting in either a need to carry impractical numbers of gels or bars, or to compromise on carbohydrate supply.  In response to this problem competitors have filled bottles with energy gels, thus making an expensive energy drink or added neutral energy mix to boost a carbohydrate electrolyte drink.  

Maybe there is a better solution?  What if we designed a drink specifically for this purpose, how much carbohydrate and electrolytes could we deliver in an isotonic solution using multiple transportable carbohydrates. That would be tasty and easy to drink when the pressure is on?
