“Vollebak” equates to all-out or giving your best in an arduous sport. It is a Dutch term that translates to “full throttle.” It indicates how much effort a sportsperson puts in when he or she gives it their all—such as completing a race or summiting a mountain.
Going “Vollebak” is to abandon all else, particularly toward the close of a race when you forego thinking of plans and operate solely on the basis of strength and willpower. It’s similar to the expression “flat out” or “burying yourself,” yet Vollebak is giving it your absolute best physical and mental effort. Endurance sports use this term commonly in Europe and demonstrate the ultimate devotion of serious competition when the cautious pacing gives way to rugged will. The term may also refer to a workout that is equal to, or exceeds, the intensity of competition.
