Both PreRace and EFS Liquid Shot were designed with flexibility in mind.  The PreRace’s small 5g serving size allows you to add this powerful formula into ANY drink.  This gives you the flexibility to use PreRace before or anytime during a race.    Open the flask, fill 3/4 with Liquid shot, add PreRace and top off with water and you are good to go. Adding a 1/2 or full scoop to an EFS liquid shot flask is a perfect tool for a high octane performance boost during a race.
