A Cycling Coach Says You’re Probably Not Eating Enough. Here’s the Fueling Strategy That Works.

Why It Matters

Proper fueling safeguards endurance athletes from energy deficiency, boosting race results and long‑term health. For the cycling industry, it highlights a growing market for science‑backed nutrition products aimed at mature riders.

Key Takeaways

• Underfueling cuts glycogen, reducing power output and recovery speed
• Calculate BMR and eat at least one‑third of calories per meal
• Consume 1 g carbs per kg body weight 60 min pre‑ride
• Take 30–60 g carbs per hour; 90 g for rides over 2.5 h
• Post‑ride protein 0.3 g/kg within 30 min accelerates muscle repair

Pulse Analysis

Endurance cycling has long been dominated by the myth that lighter bodies equal faster times, but recent research underscores a different reality. Relative Energy Deficiency in Sport (RED‑S) shows that chronic underfueling erodes muscle mass, impairs thyroid function, and elevates injury risk, especially for athletes over 40. By treating nutrition as a training variable, cyclists can preserve hormonal balance, maintain heart‑rate variability, and keep glycogen stores topped off for sustained power output. This paradigm shift is prompting sports nutrition brands to develop age‑specific formulas that address both macro‑ and micronutrient needs.

A practical fueling framework starts with a personalized basal metabolic rate (BMR) calculation, establishing a daily calorie floor. From there, athletes should distribute at least one‑third of those calories across each main meal, ensuring steady glucose availability. Pre‑ride, a simple carbohydrate load of roughly one gram per kilogram of body weight—about 68 g for a 150‑lb rider—optimizes muscle glycogen before the first pedal stroke. During rides, the American College of Sports Medicine recommends 30–60 g of carbs per hour for efforts under 2.5 hours and up to 90 g for longer sessions, delivered via gels, bars, or real‑food options every 30 minutes.

Beyond performance, adequate post‑exercise nutrition accelerates recovery and prepares the body for consecutive training days. Consuming 0.3 g of protein per kilogram of body weight within 30 minutes, paired with 1–1.2 g of carbs per kilogram over the next two hours, jump‑starts muscle repair and glycogen replenishment. For aging cyclists, this approach not only improves race outcomes but also mitigates long‑term health concerns such as osteopenia and sarcopenia. As the demographic of mature endurance athletes expands, the demand for evidence‑based fueling strategies will continue to reshape product development and coaching practices across the cycling industry.
