CLIF SHOT Bloks are the latest nutrition option for endurance athletes. Bloks come in chewable, 33 calorie cubes, making it easy to customise and track caloric and electrolyte intake during long outings and races.
"Used these as an alternative to gooey gels in training for the Brighton Marathon and during the race itself. Excellent fuel source and much easier to use than gels. They also taste a whole lot better than gels and wash down easily with water without nasty aftertaste.
Will definately be using these as primary fuel source for long runs from now on. Mountain berry flavour my own preference."
