The point of training is not to help you WIN, it is to help you FINISH comfortably. Contrary to popular belief, biking is not all leg strength and endurance. The preparation is also used to get your body used to being in the “saddle” or seat for that long of a period. Most of us could move our legs that long if we must, but our back, neck, and rear would pay the detrimental price. Those of you that want to finish fast should train appropriately.
