Cycling Fuel: Why Cyclists Eat Candy for Energy and Performance

Why do cyclists eat candy?

Cyclists often consume candy during long or intense rides as a highly efficient, rapidly absorbed source of simple carbohydrates, primarily glucose, to prevent glycogen depletion and sustain energy levels for optimal performance.

The Immediate Energy Imperative: Glucose for Glycogen

During prolonged, moderate to high-intensity cycling, the body relies heavily on carbohydrates stored as glycogen in the muscles and liver for fuel. As these glycogen stores become depleted, a cyclist experiences a significant drop in energy, performance, and cognitive function, a phenomenon colloquially known as "bonking" or "hitting the wall." To prevent this debilitating state, cyclists need to continuously replenish their carbohydrate stores. Candy, particularly varieties rich in simple sugars like glucose (dextrose) and sucrose, offers an immediate and direct source of readily available energy. Once ingested, these simple sugars are rapidly broken down and absorbed into the bloodstream, where they are then transported to working muscles to be used for immediate energy or to replenish dwindling glycogen reserves.

Candy as a Practical Fuel Source

The appeal of candy extends beyond its pure carbohydrate content, encompassing several practical advantages for cyclists on the go:

• Rapid Absorption: Simple sugars are digested and absorbed into the bloodstream far more quickly than complex carbohydrates, providing an almost immediate energy boost. This is crucial during high-intensity efforts or when energy levels are plummeting.
• Palatability and Convenience: During long rides, especially in challenging conditions, cyclists can experience flavor fatigue with traditional sports nutrition products. The familiar taste and varied textures of candy can be a welcome change. Furthermore, candy is typically lightweight, compact, easy to carry in jersey pockets, and simple to unwrap and consume while riding, even with fatigued hands.
• Cost-Effectiveness: Compared to specialized sports gels, chews, or bars, many types of candy are significantly more affordable, making them an economical choice for frequent training and racing.
• Minimal Preparation: No mixing, no blending – just unwrap and consume. This simplicity is invaluable during demanding rides.

The Science of Carbohydrate Intake During Exercise

The human body's capacity to absorb and utilize carbohydrates during exercise is limited. However, specific physiological mechanisms can be optimized:

• Glucose and Fructose Synergy: Research indicates that combining different types of simple sugars, specifically glucose (or maltodextrin, which is glucose polymers) and fructose, can enhance the rate of carbohydrate absorption. Glucose and fructose utilize different transporters in the intestine (SGLT1 for glucose, GLUT5 for fructose). By consuming both, a cyclist can absorb carbohydrates at a higher rate (up to 90 grams per hour or more) than if only one type of sugar were consumed. Many candies, such as gummy bears or jelly beans, naturally contain a mix of glucose, fructose, and sucrose (which is glucose + fructose).
• Gastric Emptying and Absorption: Simple sugars facilitate faster gastric emptying and intestinal absorption compared to more complex carbohydrates or foods high in fat, protein, or fiber. This reduces the risk of gastrointestinal distress and ensures a quicker energy supply to the muscles.
• Insulin Response During Exercise: While rapid sugar intake often triggers a significant insulin response at rest, during intense exercise, the body's physiological state changes. Muscles become more insulin-sensitive, and glucose uptake is primarily driven by muscle contraction. This means that the rapid influx of sugar is efficiently shuttled into working muscles for immediate use, mitigating concerns about significant blood sugar spikes and subsequent crashes often associated with simple sugar consumption in a sedentary state.

Strategic Candy Choices and Considerations

Not all candies are created equal for fueling purposes. Cyclists typically opt for specific types:

• Preferred Candy Types: Candies high in simple sugars, particularly dextrose (glucose) and sucrose, are ideal. Examples include gummy bears, jelly beans, hard candies, or certain fruit chews. These provide a quick, clean energy source.
• Avoid High-Fat/High-Fiber Candies: Chocolates, candies with nuts, or those high in fiber can slow down digestion and potentially lead to gastrointestinal upset during intense efforts. The goal is rapid absorption, which fat and fiber impede.
• Timing and Quantity: The strategy involves continuous intake rather than large boluses. Cyclists aim to consume 30-60 grams of carbohydrates per hour for moderate efforts, increasing to 60-90+ grams per hour for high-intensity or very long rides. Candy can be consumed in small, regular intervals (e.g., a few gummy bears every 15-20 minutes) to maintain a steady energy supply.
• Individual Tolerance: Every cyclist's digestive system is unique. What works for one may not work for another. Experimentation during training rides is crucial to determine optimal candy choices and intake rates.

Beyond the Ride: Post-Exercise Recovery

While the primary role of candy for cyclists is intra-ride fueling, simple carbohydrates also play a role in immediate post-exercise recovery. Consuming simple sugars soon after a ride can help rapidly replenish muscle glycogen stores, especially when combined with protein. However, for comprehensive recovery, a more balanced meal incorporating complex carbohydrates, protein, and healthy fats is generally preferred.

Limitations and Nuances

Despite its benefits, candy is not a perfect fueling solution for every situation:

• Nutrient Density: Candy is primarily a source of simple carbohydrates and offers minimal micronutrients (vitamins, minerals) compared to whole foods or fortified sports nutrition products.
• Gastrointestinal Distress: While designed for rapid absorption, consuming excessive amounts of simple sugars, especially without adequate hydration, can still lead to stomach cramps, nausea, or diarrhea in some individuals.
• Dental Health: Frequent consumption of sugary foods, particularly sticky candies, can contribute to dental issues if oral hygiene is not meticulously maintained.
• Not for All Rides: Candy is best suited for longer, higher-intensity rides where rapid energy replenishment is critical. For shorter, less intense rides, pre-ride fueling and water may suffice.

Conclusion: A Calculated Fueling Strategy

The practice of cyclists eating candy is not merely a indulgence, but a scientifically informed and highly effective strategy for optimizing performance and preventing fatigue during demanding rides. By leveraging the rapid absorption and metabolic pathways of simple sugars, cyclists can maintain consistent energy levels, delay the onset of bonking, and sustain peak performance. While not a substitute for a balanced diet, candy serves as a practical, convenient, and potent tool in the arsenal of an educated cyclist's fueling plan.
