There is a particular kind of stillness you only find a thousand feet up, when the wind has dropped and the only sound is your own breathing and a curlew somewhere below. Long days in the hills reward preparation more than they reward fitness, and the good news is that the preparation itself is a pleasure. Here is how to get ready for a proper upland walk — the sort that leaves you tired, muddy and quietly delighted.

Choose the Day and Know the Ground

Before anything goes into your rucksack, decide honestly what kind of day you are having. A five-mile circuit on gentle fell paths is a different animal from a twelve-mile traverse with 900 metres of ascent. Be realistic about your pace: most hill walkers manage roughly 3 to 4 kilometres per hour on the flat, plus about a minute for every 10 metres of climbing. That means a demanding route can easily take eight hours of walking, and you want to be off the high ground well before dark.

Check the mountain forecast the evening before and again in the morning. Look at wind speed as carefully as rain — a 40 mph gust on an exposed ridge will end your day faster than a shower. Tell someone where you are going, which route you plan to take, and what time you expect to be back. Then stick to that plan, or message them if you change it.

Dress in Layers, Not in Hope

Cotton kills on a hill. It soaks up sweat and rain, then sits cold against your skin. Build your outfit from three working layers instead.

• Base layer: merino wool or a synthetic wicking fabric. One spare in the pack, always.
• Mid layer: a fleece or light synthetic jacket for warmth when you stop or the cloud comes in.
• Shell: a waterproof jacket with taped seams and a hood that stays up in wind, plus waterproof over-trousers. These live in your pack even on a sunny forecast.

Wear walking trousers rather than jeans, and add a warm hat and gloves — a surprising number of hill days end because of cold hands and a cold head, not tired legs. Footwear should be worn in, with ankle support and a sole that grips wet rock. Add a spare warm layer and a dry pair of socks in a dry bag. Aim to keep a day pack under about 10 kilograms; anything heavier slows you down and tires your shoulders.

Eat Little and Often

Hill walking burns far more energy than most people expect, especially on steep ground. Eat before you feel hungry and drink before you feel thirsty. As a rough guide, aim for around 50 to 60 grams of carbohydrate for every hour of hard climbing.

• Flapjack, oatcakes, nuts, dried fruit and a decent sandwich for the summit.
• Something salty — salted peanuts or crisps — to replace what sweat takes out.
• A flask of tea or soup, which is worth its weight in morale on a cold ridge.
• At least 1.5 to 2 litres of water, more in summer, and electrolyte tablets if it is hot.

Pack a little extra food you never touch. It is the cheapest insurance you will ever carry.

Map Skills Worth Practising

A phone is a wonderful backup and a terrible primary tool. Batteries die in the cold, screens crack, and signal vanishes in exactly the valleys where you need it most. Carry a paper map at 1:25,000 scale, a compass, and a waterproof map case.

Three skills will keep you calm. First, orientate the map to the ground using your compass, so features line up as they actually are. Second, use handrails — a wall, a stream, a fence line — to guide you instead of relying on precise bearings. Third, aim off: if you are heading for a bridge, deliberately aim a little upstream, then follow the bank down, so you know which way to turn when you arrive. Practise counting paces over 100 metres on the flat and on a slope. It is a small skill that feels like magic in mist.

Safety Nets You Hope Not to Use

Carry a head torch with spare batteries, a whistle, a small first aid kit, and a lightweight emergency shelter or bivvy bag. Add a fully charged phone and a power bank. In a genuine emergency in the UK, dial 999, ask for the police, and then ask for mountain rescue — they will want your location, ideally a grid reference.

Know the signs of hypothermia and of heat exhaustion, and be willing to turn back. Turning around is a skill, not a failure. The hill will still be there next month.

Walking Slowly, Arriving Happily

Here is the part that matters most. Plan in slack. Stop every hour, even for five minutes, to drink, eat and let your shoulders drop. Slow your pace on the ascents to something you could hold a conversation at. Use trekking poles if your knees complain on descents — they are not a sign of weakness, just arithmetic.

And then, deliberately, do less. Sit on the summit for twenty minutes rather than ten. Notice the moss, the ring ouzel, the way cloud pours over a col. That is the whole point of a long day out: not the distance covered, but the pace at which you were allowed to meet the place. Prepare well, and the hills will let you slow right down.
