Ultra distance events have special needs beyond what a typical race or training ride needs. Supplementary carbs are imperative to make up the massive amount of energy used that would be impossible to replace with whole food. Sodium is needed to balance salt lost in sweat. Water drinking must balance lost sweat while avoiding hyponatremia. This video aims to help ultra distance cyclists develop an optimized dry drink mix to carry along and resupply on the road for those very, very long rides while meeting those tough demands.
