The Complete Guide to Eating Before Ascending a Munro

If you're planning to climb a Munro, you will need to eat properly to maintain your energy levels and avoid bonking. This article covers everything you need to know, from what to eat before your ascent to how to refuel while you hike.

Understanding Bonking

“Bonking” is a term used in mountaineering when a climber’s energy levels drop sharply, resulting in sluggishness and fatigue. This happens when your body runs out of glucose, the primary source of energy. Proper nutrition is crucial to prevent this from happening.

Your Pre-Hike Planning

Getting ready the night before your climb is vital. A well-rounded meal can help ensure you start the day with a full tank of energy. Here are some suggestions:

The Night Before

Consume a high-carb meal, such as a pizza and spaghetti, to store glycogen in your muscles. This will help your body maintain energy levels during the hike. Avoid alcohol, as it can disrupt your sleep and lower your energy levels. Make sure you go to bed early so you can get a good night’s rest.

The Morning of Your Climb

Plan a hearty breakfast to give you sustained energy. Syrup pancakes, eggs, and a variety of high-calorie snacks like MM’s, dried fruit, and nuts should be part of your breakfast. These snacks provide both immediate energy and long-term fuel as you hike.

Hydration and Snacking Mid-Hike

During your hike, it's important to stay hydrated and continue to fuel your body. High-calorie, low-sugar snacks like a Snickers bar or raisins can be a source of quick energy. Try to choose snacks that won't easily get soggy or messy, such as wraps or energy bars.

Eating on the Go

While you can eat at the summit, it's often beneficial to have a small meal or snack along the way. Personally, I prefer cucumber, carrots, and snap peas, as they provide a good mix of nutrients and are easy to carry. Wraps are another great option, as they are less likely to get messy compared to traditional sandwiches.

Proper Hydration

Staying hydrated is crucial during a long hike. It’s important to drink water consistently throughout the day, even if you don't feel thirsty. Consider adding the juice of an orange and a splash of salt to your water bottle for additional electrolytes and flavor.

Recovery on the Descent

After your climb, it's important to eat properly again. Save some high-calorie snacks like another Snickers bar and a couple of individual raisin boxes for your descent. This will help replenish your energy levels and support your recovery.

Remember, everyone’s body is different, and what works for one person may not work for another. Experiment with different types of food and snacks to find what works best for you. Whether you're a seasoned hiker or a beginner, proper nutrition can make all the difference on your next Munro climb.
