The Fueling Strategy: Before the Ride
Success on a 50-mile ride starts long before you get on the bike. The primary goal is to ensure your body’s glycogen stores—the stored form of carbohydrates in your muscles and liver—are fully topped off. Neglecting this crucial step is a surefire way to 'bonk,' experiencing a rapid and debilitating loss of energy midway through your ride.
The Evening Before
Your pre-ride fueling should begin with a generous, carbohydrate-rich dinner the night before. Focus on easily digestible, slow-burning complex carbohydrates rather than heavy, fatty, or overly spicy foods that could cause digestive issues. Keep portion sizes normal to avoid overeating and disrupting your sleep.
Good options include:
- Pasta with a light, tomato-based sauce.
- Brown rice with lean protein like grilled chicken or tofu.
- Sweet potatoes.
The Morning of the Ride
Two to three hours before your ride, consume a balanced breakfast rich in complex carbohydrates and moderate in protein, while being low in fat and fiber. This timing allows for proper digestion and ensures a steady release of energy. If you are nervous and can't stomach a full meal, opt for a liquid-based option like a smoothie.
Good breakfast options include:
- Oatmeal with fruit and a handful of nuts.
- A bagel with peanut butter and honey.
- Scrambled eggs with toast.
Just Before the Ride
In the final 30–60 minutes before you start, have a small, easily digestible carbohydrate snack to give you a quick energy boost. A banana is a popular and effective choice for this final pre-ride fuel-up.
On-the-Bike Fueling: The During-Ride Plan
Your body's glycogen stores last for roughly 60–90 minutes of continuous riding. For a 50-mile ride, you will need to consistently refuel to avoid running out of energy. The golden rule is to eat and drink 'little and often'—don't wait until you're hungry or thirsty.
Carbohydrate Intake
Aim for 30–60 grams of carbohydrates per hour for an average-intensity ride. This can be a mix of solid food and energy drinks. Start your fueling within the first 45 minutes of the ride.
Hydration Strategy
Proper hydration is critical for performance and digestion. For rides over 90 minutes, plain water is not enough; you need to replace lost electrolytes.
- Fluid Intake: Target 500–750 ml of fluid per hour, adjusting for weather conditions and individual sweat rate.
- Electrolytes: Use a sports drink or add electrolyte tablets to your water, especially on hot days.
- Alternating Bottles: Many cyclists carry one bottle with a sports drink and another with plain water.
Choosing Your On-Bike Fuel: Real Food vs. Sports Products
There are many options for fueling during your ride, and what works best is a personal preference. Experiment during training to find what agrees with your stomach.
| Feature | Real Food | Sports Products (Gels, Chews) |
|---|---|---|
| Digestibility | Varies; can be slower depending on fiber/fat content. | Formulated for rapid and easy absorption. |
| Convenience | Can be messy to prepare and eat while riding. | Small, portable, and easy to consume on the go. |
| Cost | Generally more cost-effective. | Typically more expensive per serving. |
| Palatability | Offers a variety of flavors and textures to combat 'flavor fatigue.' | Often sweet and can become tiresome over a long ride. |
| GI Issues | Less likely to cause GI upset if chosen correctly (low fiber/fat). | High sugar content can cause stomach distress for some. |
Post-Ride Recovery: Refueling and Repair
Your nutrition plan isn't over when you finish the ride. The recovery phase is essential for repairing muscles and replenishing energy stores, especially if you plan to ride again soon.
The Golden Hour
Within 30–60 minutes of finishing, consume a recovery snack or meal rich in both carbohydrates and protein. Carbohydrates replenish depleted glycogen, while protein aids in muscle repair. A common recommendation is a 3:1 or 4:1 carb-to-protein ratio.
Recovery Meal Examples
- Chocolate milk provides a near-perfect carb-to-protein ratio.
- Smoothie with banana, protein powder, and milk.
- Greek yogurt with granola and berries.
Sustained Replenishment
A few hours later, eat a well-balanced meal containing a mix of all three macronutrients. This ensures your body continues to recover and rebuild effectively.
Avoiding Gastrointestinal Issues
Stomach problems are a common concern for endurance cyclists. Here are some tips to prevent them:
- Practice in Training: Never try a new food, gel, or hydration mix on race day.
- Avoid High-Fat/Fiber: High-fiber and high-fat foods slow digestion and can cause discomfort. Save these for your pre-ride meal the night before.
- Stay Hydrated: Dehydration can slow digestion and increase the risk of GI distress.
- Don't Overeat: Consuming too many calories or carbs at once can overwhelm your digestive system. Stick to a 'little and often' approach.
Conclusion: Planning for a Strong Finish
Successfully eating for a 50-mile bike ride hinges on strategic fueling and hydration at every stage. From topping off your energy stores with a carb-rich meal the night before, to consistently feeding and hydrating during the ride, and finally, aiding muscle repair with a crucial post-ride snack—every step matters. By listening to your body and practicing your personalized plan during training, you will not only avoid the dreaded bonk but also maximize your performance and enjoyment on the bike.
