Had 2 of the 3 bloks in this Clif Shot Bloks thing. It's kind of jelly-like or gummy-like. It's an electrolyte energy booster to get you through an intense workout. This would be awesome to keep in a pouch on a 5K for a halfway through boost. I punked out a bit by the end of Boot Camp today so my trainer, Bridget, had me eat 2 of the bloks at the end of my workout.
