When should I start fueling during a bike ride?
Begin consuming carbohydrates within the first 30-60 minutes of riding, before you feel hungry or low on energy.
How does weather affect my nutrition needs while cycling?
Hot and humid conditions increase fluid and electrolyte needs significantly, while cold weather may reduce thirst but still requires adequate hydration.
