How to Fuel for the 3 Peaks Challenge: Your Complete Nutrition Strategy

4 min read

The National 3 Peaks Challenge requires hiking a total distance of 23 miles (37km) and ascending over 3000 metres within 24 hours, demanding a precise fueling strategy. Knowing how to fuel for the 3 Peaks Challenge is critical for maintaining energy, preventing fatigue, and ensuring you can complete this demanding ultra-endurance event.

Quick Summary

A comprehensive nutrition plan is essential for the 3 Peaks Challenge, including pre-event carb loading, on-hike fueling with slow and fast-release energy, and post-challenge recovery. Proper hydration and electrolyte management are also key components for success.

Key Points

  • Start early: Begin your fueling strategy days before the event by increasing your carbohydrate intake to fill your glycogen stores.

  • Graze, don't gorge: During the hike, eat small amounts of food frequently—around 30-60g of carbs per hour—to maintain stable energy levels and aid digestion.

  • Mix your fuel sources: Combine slow-release energy from real foods like flapjacks and nuts with fast-acting sugars from gels or sweets for quick boosts.

  • Stay hydrated and electrolyte-rich: Drink water constantly, aiming for 500ml per hour, and use electrolyte tabs or salty foods to replace lost minerals.

  • Recover between peaks: Use the bus journey to consume a hot meal or protein shake, kickstarting recovery for the next mountain.

  • Test everything first: Never try new foods, gels, or hydration strategies for the first time during the challenge itself.

Preparing Your Body: The Pre-Challenge Fueling Plan

Your preparation for the 3 Peaks Challenge should begin long before you set foot on Ben Nevis. A smart nutrition strategy can set you up for success, while poor planning can lead to early fatigue. The primary goal is to maximize your body's glycogen stores, the readily available fuel for your muscles.

One week out: Taper down your training and focus on increasing your carbohydrate intake. Prioritize complex carbs like pasta, rice, potatoes, and whole grains.

The night before: Have a carbohydrate-rich, but not overly heavy, evening meal that your body is familiar with. Avoid introducing new foods that could cause stomach upset. Think pasta with a light tomato sauce or baked potatoes with lean protein.

Breakfast on challenge day: Eat a balanced breakfast of slow-release carbohydrates and some protein about 2 hours before you start. Oatmeal with fruit and nuts or scrambled eggs on toast are excellent choices. Don't skip this meal, as it's the foundation for your first peak.

Fuelling on the Trail: Eating Little and Often

During the hike, the strategy shifts to consuming small, frequent amounts of food to keep your energy levels stable. Your body can only absorb a limited amount of carbohydrates per hour, so grazing is more effective than large meals. Aim to consume between 30-60 grams of carbohydrates per hour.

What to pack in your rucksack:

  • High-energy snacks: Nuts, dried fruit, trail mix, and flapjacks offer a good mix of carbohydrates and healthy fats for sustained energy.
  • Fast-release sugars: Jelly babies, fruit pastilles, or energy gels are perfect for quick boosts during tough sections or near the summit.
  • Savoury options: Small sandwiches with peanut butter or lean meat, cheese, and crackers can be a welcome change from sweet foods, preventing 'sweet fatigue'.
  • Performance products: Energy gels and chews can be highly effective, but you must test them during training to ensure they don't cause gastrointestinal distress.

Hydration: Your Performance Lifeline

Dehydration is a major risk during the 3 Peaks Challenge and can quickly compromise performance. The rule is simple: drink little and often, don't wait until you're thirsty. A good guideline is to aim for around 500ml of fluid per hour of strenuous exercise.

Your hydration system:

  • Water bladder: A hydration bladder is often easier than bottles, allowing you to sip continuously without stopping. Carry at least 2-3 litres of water, and ensure you can refill at support stops.
  • Electrolytes: Adding electrolyte tablets to one of your water bottles can help replace the salts and minerals lost through sweat, preventing cramping and maintaining fluid balance. This is especially crucial in warmer weather.

Between Peaks: Refueling and Recovery

Once you return to your support vehicle after each mountain, your focus should be on rapid recovery to prepare for the next climb. While time is limited, this is a prime opportunity for refueling.

Between-mountain meals:

  • Hot food: A hot, savory meal like pre-cooked pasta or a rice pot can be a huge psychological and physical boost. Many outdoor-specific dehydrated meals are available and can be quickly prepared.
  • Carbs and protein: Aim for a 3:1 ratio of carbohydrates to protein to replenish glycogen stores and aid muscle repair. A milkshake or protein shake is a quick, easy way to get both.
  • Rehydration: Use this time to drink plenty of fluids and consume more electrolytes before you start the drive to the next peak.

Fueling Strategies: Real Food vs. Gels

Feature Real Food (e.g., sandwiches, nuts) Energy Gels/Chews
Energy Release Slower, more sustained release Faster, quicker energy spike
Digestibility Slower digestion, less risk of sugar crash if balanced Can cause stomach upset if consumed too quickly
Taste Fatigue Wide variety prevents taste fatigue Sweet, repetitive taste can lead to aversion
Nutrient Density Often contains a broader range of nutrients, fiber, and protein Focused primarily on carbohydrates and electrolytes
Convenience Can be bulky to carry and messy to eat Portable, easy to consume on the move

The Recovery Meal: Rebuild and Repair

After completing the final peak, your body will be exhausted and in need of proper nutrition to recover. Don't neglect this final stage of fueling.

  • Replenish: Consume a substantial meal high in complex carbohydrates and protein within 1-2 hours of finishing. This helps kickstart muscle repair and glycogen replenishment.
  • Rehydrate: Continue to drink plenty of water and electrolytes. You've been sweating for a long time, and rehydration is key to feeling better.

Conclusion

Fueling for the 3 Peaks Challenge is an essential component of your preparation, just as important as your physical training. By carb-loading effectively, adopting a 'little and often' grazing approach on the trail with a mix of fast and slow-release energy, staying meticulously hydrated with water and electrolytes, and planning your between-peak and post-event recovery meals, you can significantly boost your chances of a successful and more enjoyable challenge. Practice your nutrition plan during your training hikes to discover what works best for your body, ensuring there are no surprises on the big day. A well-fueled body is a strong body, ready to conquer any mountain. For more detailed training and preparation advice, consider exploring resources from organizations like Challenge Central.

Frequently Asked Questions

Aim for a breakfast with slow-release carbohydrates and some protein, such as porridge with fruit and nuts or scrambled eggs on toast. Eat it 2 hours before you start to allow for digestion.

The general recommendation is to drink around 500ml of fluid per hour of exercise. It's crucial to sip little and often throughout the day, using a hydration bladder to make it easier to access while walking.

Energy gels offer a quick energy boost but can cause stomach issues. Real food provides a slower, more sustained release of energy and variety to prevent 'sweet fatigue'. A mix of both is often the best strategy.

Focus on a savory, carbohydrate-rich meal that also contains protein for muscle recovery. Pre-cooked pasta pots, rice dishes, or specialized outdoor hot meals are great options for consumption in the support vehicle.

Practice your nutrition plan during training to let your body adapt. Consume food and fluids in small, frequent amounts. Use electrolyte drinks and consider low-FODMAP foods if you have sensitivities.

During the hike, focus primarily on carbohydrates for energy. While protein is important for recovery, it's less critical during the actual physical exertion. Save heavier protein intake for the rest breaks and post-challenge meal.

'Sweet fatigue' is an aversion to overly sweet energy products that can develop during long endurance events. To avoid it, pack a variety of savory, salty, and texturally different foods, such as crackers, jerky, and salted nuts, alongside your sweet snacks.
