While it's tempting to search for a one-size-fits-all answer to fueling endurance rides, the truth is that individual needs and preferences vary greatly. Relying on a single "best" food may not provide the optimal mix of nutrients for your specific situation.
During a 4-hour Zone Two session at 270-290 watts with a heart rate between 130-140, your body will require a steady supply of carbohydrates for energy, as well as some protein to support muscle repair and electrolytes to replace those lost through sweating.
However, it's crucial to listen to your body and consume what works best for you. Some cyclists may prefer energy gels or bars, while others may opt for real food like bananas, dates, or energy chews. Even within these categories, there's a wide range of options with varying amounts of sugar, fiber, and other nutrients.
Additionally, practicing your fueling strategy during training is essential to avoid unexpected issues during races. So, instead of focusing on a single "best" food, experiment with different options, learn what works best for you, and dial in your personalized nutrition plan.
