Why is endurance fueling still so misunderstood?
As a registered dietitian with 5 years of experience and an avid cyclist, I've been diving into endurance fueling strategies lately, and I'm left questioning so much of what's out there. It seems like there's a lot of dogma surrounding how to fuel properly for long rides, yet much of it feels outdated or just plain incorrect.
For instance, the common advice around consuming 30-60 grams of carbs per hour during endurance activities seems to be based on a narrow view of metabolism. Research, like the one from Jeukendrup, suggests that higher carb intake can enhance performance, but they also acknowledge the importance of individual variability. So why do so many coaches still stick to the one-size-fits-all approach? Some of us have different metabolic rates, and some of us might even tolerate higher carb loads better than others. This is particularly critical for cyclists who are training at high intensities and for longer durations.
Additionally, I've noticed that there's still a lot of confusion about pre-ride fueling. Many people stick to the idea of loading up the night before and then eating minimally the day of. But research shows that a balanced meal with carbs and protein closer to the ride can actually enhance performance. Why do we still see so many cyclists opting for a granola bar and calling it a day? It's frustrating to see such a disconnect in the community between scientific findings and actual practice. I'm curious about others' experiences and thoughts on this, is there any movement toward a more individualized approach in your coaching practice? What do you think needs to change in the common narrative around endurance fueling?
