Is the widely-held notion that road cyclists have a tendency to overhydrate during indoor sessions due to their supposed professional ethos, and does this potentially pose more harm than good in comparison to simply listening to the bodys natural thirst signals, or is this merely a myth perpetuated by those who ride on the dark side – mountain bikes – to further discredit the asphalt warriors, and what role do electrolytes play in this delicate hydration balance, or should we just stick to the tried and true method of weighing ourselves before and after a session to determine our optimal hydration levels, and why do some manufacturers insist on touting their hydration systems as the best when the science suggests otherwise, or am I just sipping on a different flavor of Kool-Aid.
