Sodium depletion via sweat is the primary reason for muscle cramping in endurance athletes. By adding Clif Shot Bloks to your activities, you get sodium, carbohydrates and electrolytes, in 1 easy-to-ingest solution to help counteract the losses in your sweat. The Bloks can be eaten 15-30 minutes prior to activity to increase blood sugar levels, and then every 20-30 minutes during activity to maintain energy levels. Bloks come in chewable, great-tasting, 33-calorie cubes, making it easy to customize and track caloric and electrolyte intake during long outings and races.
