What to wear and carry for Ben Nevis, Scafell Pike and Snowdon in 24 hours. Boots, layers, pack and headtorch covered.
The National Three Peaks Challenge asks you to climb the highest peaks in Scotland, England and Wales within 24 hours: Ben Nevis (1,345m), Scafell Pike (978m), and Snowdon/Yr Wyddfa (1,085m). Over 25km of walking and 3,000m of ascent, with driving time between peaks eating into the clock. Completing it requires physical preparation, solid logistics, and kit that won't let you down.
The boots you choose matter more on this challenge than on almost any other walk. You'll be covering serious mountain terrain in the dark, potentially in poor weather, with fatigue accumulating through the night. This is not the occasion for trail runners you've never tested in the wet.
Three Summits, One Night: What the Challenge Demands
The Three Peaks isn't a technical mountaineering challenge, but it is three serious mountain walks done back-to-back under time pressure, partly at night. Ben Nevis can have near-freezing temperatures at the summit in any month. Scafell Pike is notoriously boggy and navigationally demanding in poor visibility. Snowdon's Pyg Track is rocky and can be slippery when wet.
The Three Peaks attracts participants across a wide range of mountain experience, from seasoned hillwalkers adding it to a long list of objectives to charity fundraisers for whom this will be the biggest walk they have ever done. What the mountains require is the same regardless: kit that will perform across three serious ascents in changeable conditions. Not the most technical option available, but not cut-price alternatives either.
Boots for Three Mountains in 24 Hours
A solid three-season walking boot with ankle support, a waterproof membrane, and a reliable outsole for wet rock and grass. That is what this challenge requires.
What to look for: full ankle coverage, a waterproof membrane (Sympatex or Gore-Tex), and an outsole with a lug pattern designed for wet mountain terrain. The boot must be fully broken in before event day. See: How to Break In Walking Boots
Socks: a merino or synthetic hiking sock with adequate cushioning. Carry a spare pair. Changing into dry socks at the Scotland-to-England transfer is one of the most effective blister prevention measures available and costs nothing.
Insoles: if you're prone to arch fatigue or heel issues, a specialist insole can make the difference between finishing comfortably and finishing in pain. See: Insoles for Walking Boots: Customising Your Fit
Dressing for Three Different Summits
Mountain weather on all three peaks can be poor even in summer. Night temperatures on Ben Nevis summit can approach freezing in June. The layering system below is the minimum; err on the side of too much rather than too little.
- Base layer: merino or synthetic, moisture-wicking. Not cotton
- Mid layer: fleece or lightweight insulation jacket
- Waterproof jacket: taped seams, a hood, packable enough to go in your day pack
- Waterproof trousers: Scafell Pike in the rain without waterproof trousers is a miserable experience
- Gloves and hat: summit temperatures on Ben Nevis can drop to near freezing on a summer night. Your hands will be cold on the descent
What to Carry on Each Mountain Leg
A day pack of 20 to 30 litres is adequate. The Three Peaks is a supported challenge: the minibus carries overnight kit and resupply. You carry what you need for each individual mountain.
Essential pack contents for each peak:
- Water: minimum 1.5 litres on Ben Nevis, which has no reliable en-route water sources
- Food: high-density snacks, energy bars, sandwich at minimum. You're burning significant calories across 24 hours
- Headtorch: with fresh or charged batteries. See below
- Spare layers: even if conditions at the start are good
- First aid: blister treatment, paracetamol, an emergency foil blanket
- Phone: fully charged, with an offline map downloaded, and emergency contacts stored
Navigating Ben Nevis and Scafell Pike in the Dark
Ben Nevis will almost certainly be climbed in darkness if you're on the standard 24-hour attempt, and the descent after summit requires a reliable headtorch. Scafell Pike often follows in darkness too. A headtorch is essential kit. Carry spare batteries or a charged power bank.
Fuelling a 24-Hour Challenge
You'll cover the challenge across roughly 24 hours of effort and travel. Calorie burn is significant and sustained. Planning nutrition around the mountain stages matters.
At each van stop between peaks: eat something substantial, not just snacks. Change socks. Rest your feet for ten minutes if time allows. Hydration management across a 24-hour period is easy to neglect; drink consistently rather than waiting until you feel thirsty.
Getting Ready for Event Day
The kit can only do so much. Walking fitness, time on the hills, and having worn your boots on several similar days before event day are the real determinants of a good experience.
Suggested minimum preparation: three to four walking days in the months before the challenge, at least one of which is a full day in the hills on mixed terrain. Cover the distance you'll walk on each peak in training, in the same boots, before attempting the challenge.
Timings and Target Splits
The standard 24-hour challenge runs clockwise: Ben Nevis, Scafell Pike, Snowdon. Typical target splits for a comfortable finish:
- Ben Nevis: 4.5 to 6 hours (ascent and descent)
- Scafell Pike: 3 to 4 hours
- Snowdon (Pyg Track): 3 to 4 hours
- Driving: 8 to 10 hours total
Most participants do the challenge as part of a charity event with an organised group and transport. Independent attempts require your own vehicle logistics and a driver for each leg.
