Mountain Course Nutrition Scotland: What to Eat and Drink
Let's be honest: most people spend weeks sorting their kit list for a mountain course in Scotland and then forget about food until they're standing in the rain on day one with nothing in their stomach. Your guide notices. Your legs notice even faster. Good mountain course nutrition in Scotland doesn't need to be fancy, but it does need a plan. On a multi-day course on Skye or up on Ben Nevis, you're burning serious energy from first light to last, often in wind that steals body heat faster than you'd think. Get the food and drink right and the days feel manageable. Get it wrong and you're slow, grumpy, and making sloppy calls on steep ground. Here's what I actually tell people to eat and drink, and why it matters.

Quick Takeaways
Key Insight | Explanation |
|---|---|
Eat a proper breakfast | Slow carbs and a bit of fat get you moving before the first climb. Snacking on the hill won't fully make up for skipping it. |
Carbs are your main fuel | Build every snack and meal around carbs, since your muscles reach for them first when the day gets hard. |
Snack little and often | Small bites every hour beat one big lunch stop. Cold hands make big bags of food a chore. |
Drink before you feel thirsty | Cold air hides thirst, so sip steadily from the start of the day rather than catching up at lunch. |
Add salt on long, sweaty days | Plain water alone can leave you short on salt. A salty snack or an electrolyte tablet helps on the big days. |
Carry one cold-proof emergency snack | Keep something inside your jacket so it doesn't freeze solid when you're running low on the ridge. |
Why Fuelling Matters More Than You Think
Here's the thing about a multi-day course: you're not one long walk. You're a string of hard days stacked on top of each other, and each day you dig a little deeper into the tank. Day one feels easy. By day three, the small gap between what you eat and what you burn shows up as heavy legs and short tempers.
Scotland adds its own twist. Wind chill, wet kit, and short winter days mean you burn more energy than you'd expect, even when you're standing still. Your body spends fuel just keeping warm, and a soggy, freezing belay can cost you more than the climb itself.
Energy Needs on Hill Days
I won't pretend there's one perfect number for everyone. Body size, pace, pack weight, and temperature all change the picture. What I can tell you is that a day of ice climbing or a steep ascent with a loaded pack eats through far more than a casual walk. Most people underestimate this by a lot.
If you're unsure, eat more than you think you need on the first two days. Your appetite will tell you soon enough whether you're on track.
The Quiet Cost of Under-Eating
Under-eating doesn't always feel like hunger. It shows up as clumsy hands, slow decisions, and a sudden urge to sit down on a bad slope. That's exactly when you need your head clear. Good nutrition is a safety thing, not a comfort thing.
"The importance of adequate caloric and fluid intake must be rated at least as highly as that of oxygen." That's Dr Griffith Pugh, as quoted in UIAA mountain medicine advice on nutrition, and it's the single best reason to take food seriously on a course.
Breakfast Before the Day Starts
Breakfast is where most courses go wrong. People are rushed, the stove is slow, and a cup of tea feels like enough. It isn't. You're starting a long day on a near-empty tank, and the first few hours decide whether you feel strong or feel like you're dragging a sack of potatoes up the hill.
What I Eat at Breakfast
My go-to is porridge made with milk or a proper oat base, with a handful of nuts, some dried fruit, and a spoonful of nut butter stirred in. You get slow-release carbs, a bit of fat, and some protein, which keeps you going without the sugar crash. Instant options are fine if you're short on time, but add something to them so they're not just hot sugar water.
Bread, peanut butter, and a banana is another easy choice. Keep it simple and eat it sitting down if you can. Standing up and chewing while you pack your bag is how half of breakfast ends up in the car park.
Timing Your Morning Meal
Eat about an hour before you start moving, then keep a snack in your pocket for the first stretch on the hill. If your course starts early and you're tempted to skip it, set the alarm ten minutes earlier. The sandwich you eat in the car park beats an empty stomach on the ridge every single time.
Pro tip: Pack your breakfast in a container you can eat from straight away. Fiddling with lids and wrappers in the cold wastes time and warmth you won't get back.
Snacks and Fuel on the Move
Once you're walking or climbing, food has one job: keep energy steady. Big lunches are a trap. They make you sleepy and heavy, and then you're trying to chew a sandwich in a gale. Little and often works far better.
Carbs Are Your Main Fuel
For active days, carbs do most of the heavy lifting. Endurance sport guidance often lands around 30 to 60 grams of carbohydrate an hour for sustained effort, and that's a useful ballpark if you're not sure where to start. You'll get there with things like jelly sweets, flapjack, dried fruit, or energy chews. Don't chase the number to the gram. Just make sure something carby goes in regularly.
Gels work too, but many people find them sickly after a few hours. Mix them with real food so your mouth doesn't get bored and your stomach doesn't revolt.
Real Food That Survives a Scottish Day
Cold changes what food is good for. Chocolate turns to brick, and cheese goes rubbery and sad. Stick with things that stay chewable at low temperatures, like flapjack, oatcakes with cheese or peanut butter, dried mango, and salted nuts. Wrap everything in a zip bag so it doesn't get soggy from wet gloves.
A sandwich in an outer pocket will freeze on a winter day. Keep it inside your jacket, against your body, if you want it to stay edible at lunch.
Pro tip: Eat before you feel hungry. By the time your stomach's growling, you're already behind on energy, and catching up on a steep slope is hard work.
Hydration: Drinking Enough Without Overdoing It
Dehydration sneaks up on you in winter. Cold air is dry, you're breathing hard, and nobody feels thirsty in a blizzard. So people drink less, which is exactly the wrong move. Drinking regularly from the start of the day matters far more than gulping a litre at lunch.
How Much and How Often
Sip little and often rather than trying to catch up later. A simple check is your urine colour. Pale straw means you're in a good place, and dark yellow means you're behind. It's not perfect, but it's a useful signal when you're tired and nobody's keeping score.
Salt, Electrolytes, and Long Wet Days
On long, sweaty days, plain water isn't always enough. Salty snacks like crisps, salted nuts, or a pinch of salt in your flask can help replace what you're losing. Electrolyte tablets are handy too, but read the label and don't overdo it. Drinking loads of plain water with no salt at all can cause its own problems.
Keeping Water From Freezing
Water bottles freeze in Scottish winters. Store them upside down so any ice forms at the base instead of blocking the lid, and keep one bottle inside your jacket. A flask of warm drink is a lifesaver on a cold belay, and tea or hot chocolate counts toward your fluid total.
Comparing Your Fuel Options
Not all fuel is equal on a course. Here's how the main options stack up for the kind of days you'll have on Skye or around Fort William.
Fuel Option | Best For | Watch Out For |
|---|---|---|
Gels and energy chews | Fast carbs during hard climbing or steep ascents | Sickly sweet after a few hours, and can upset your stomach if you go heavy |
Flapjack and oat bars | Steady energy on long walk-ins | Can be dry and crumbly, so always carry a drink with them |
Sandwiches and wraps | Proper lunch stops and a real refuel | Freezes and gets soggy, so keep them inside your jacket |
Dried fruit and nut mix | Quick snacks with carbs and fats together | Easy to overeat, and dry fruit can be tough on lips in cold wind |
My advice: carry two types of snack. One sweet and fast, one savoury and filling. Your taste buds will thank you by day four, when everything starts to taste like cardboard.
Evening Meals and Recovery After Long Days
The day ends, but your nutrition job doesn't. Your muscles are tired and your body wants to rebuild, so a proper evening meal matters. Think carbs, some protein, and plenty of fluid. You're not dieting on a course, so don't skimp.
A Proper Dinner Without the Fuss
Pasta with a tin of fish, a bean-based chilli, rice with chicken, or a hearty stew all work well. They're easy to cook on a small stove, and they fill you up after a hard day. Add a bit of cheese or a splash of olive oil for extra energy, because fat is calorie dense and handy when the temperature drops.
Recovery Snacks Before Bed
A small snack before bed helps. Something like a glass of milk, a handful of nuts, or cheese on a cracker will do the job. It's not a big deal, but it helps you wake up less wrecked, which is what you actually want on the next morning.
Eating Well When It's Cold and Wet
Scottish winter adds a layer of difficulty that summer walks don't. Cold food is less appealing, cold hands struggle with wrappers, and wet days tempt you to skip meals altogether. You need a plan for those days, not just hope.
Hot Food in a Flask
A flask of soup, porridge, or hot chocolate can change your whole afternoon. Warm food is easier to eat when you're stuck on a cold ledge, and the heat helps you feel warmer too. Fill it with something you actually want to drink, not just the thing that looks healthy on paper.
Opening Packets With Cold Hands
Practise opening your snacks at home while wearing gloves. Pre-open the things you know you'll want, like the flapjack, and leave the stubborn packets for the top of the hill. It sounds small, but it stops you giving up on food altogether.
Pro tip: Keep one emergency snack in an inside pocket. Choose something you can eat even if it's a bit chilly, like a cereal bar or a chunk of hard cheese, rather than a bar that shatters when you bite it.
Common Mistakes I See on Every Course
After enough courses, you start spotting the same errors. Most are small, and all of them are fixable. Here are the ones I see most often on multi-day trips in Scotland.
Relying on One Big Meal
Lots of people pack a huge lunch and then eat nothing else until camp. By the afternoon they're flat, and their energy has crashed. Spread your food across the whole day instead, even if it feels like grazing.
Only Drinking at Camp
Wait until you're back at base to drink and you've already fallen behind. Dehydration makes the next morning harder too. Drink on the move, even when it feels pointless.
Ignoring Pace and Food Stops
If your guide calls a food stop, take it. They're watching the group, the weather, and the terrain. A quick two-minute snack stop saves the whole group from a rushed, tired decision later on.
Frequently Asked Questions
What should I eat the night before a multi-day course in Scotland?
Have a normal, filling meal with carbs and a bit of protein, like pasta with chicken or a rice bowl with vegetables. Avoid anything very rich or very spicy, and don't try a new food on the eve of a big day. Familiar food is your friend here.
How much should I drink on a winter mountain course?
There's no magic litre count that works for everyone. Aim to sip steadily from the start of the day, and use pale urine as a rough guide. Cold air hides thirst, so don't wait until you feel thirsty to drink.
Are energy gels necessary for winter climbing?
No, they're not essential. Gels are useful on hard days when you need fast carbs, but real food like flapjack, dried fruit, and sweets works just as well for many people. Test any new product on a training day before you rely on it on the hill.
What's the best food for a long day of ice climbing?
Go for a mix of chewy carbs, salty snacks, and something hot in a flask. Keep sandwiches or wraps inside your jacket so they don't freeze. Small, frequent bites work better than one large lunch when your hands are busy and cold.
Should I bring my own food or will the course provide it?
Ask your guide before you book so you know exactly what's included. Snacks and lunches on the hill are usually something you bring yourself, so plan on carrying your own fuel for each day. Good planning here means fewer surprises halfway up a hill.
