What are the key factors to consider when determining optimal hydration strategies for long zone 2 rides, and how can cyclists effectively monitor and adjust their hydration levels to maximize performance and delay the onset of fatigue?
In particular, Id like to explore the role of electrolyte balance, fluid intake, and individual sweat rates in maintaining optimal hydration levels during prolonged periods of moderate-intensity exercise. Are there any specific hydration protocols or tools that have been shown to be effective in this context?
Additionally, how do changes in environmental conditions, such as temperature and humidity, impact hydration needs during long zone 2 rides, and what strategies can cyclists use to adapt their hydration plans accordingly?
