What effect does not using artificial stimulus have during long rides?

Not using artificial stimuli such as caffeine or other energy-boosting substances during long rides improves focus and alertness in a natural and sustainable way. Relying on these substances can lead to peaks and crashes in energy levels, which may impair your ability to concentrate effectively over time. Instead of depending on temporary boosts, maintaining a steady level of alertness can help in staying attentive to the road and responding to changing conditions without the risk of over-stimulation or sudden fatigue. This approach promotes a more consistent and balanced state of mind, which is crucial for safe riding over long distances.
