What You're Actually Signing Up For

The South West Coast Path runs roughly 630 miles from Minehead in Somerset to Poole Harbour in Dorset, and it is routinely described as one of the toughest long-distance trails in Britain. That reputation is earned. The path climbs and descends something in the region of 35,000 metres over its full length — more than four times the height of Everest — and almost none of it is flat. A typical day delivers you into a steep wooded valley, out again onto an exposed headland, down a set of granite steps, and up once more.

Multi-day sections are far more achievable than the whole thing, and many walkers tackle a week or a fortnight at a time. But whichever stretch you choose, the planning is the same. Assume rough, undulating ground, few flat stretches, and villages that are further apart than the map suggests.

Train on Hills, Not Just Distances

If you can walk 15 flat miles, that does not mean you can walk 12 miles on the coast path. The constant climbing loads your calves, quads and hip flexors in a way that road walking never does, and the descents hammer your knees and toes.

• Build a base first. Aim for three or four walks a week for at least eight weeks before you go, mixing short fast walks with one long one.
• Add hills deliberately. Hill repeats — walk up, walk down, repeat — are dull but effective. Staircases, multi-storey car parks and steep urban streets all work.
• Train with your pack. Start at half your intended weight and build up. Your shoulders and hips need time to adapt, and your balance changes once you're loaded.
• Practise back-to-back days. Two consecutive 10-mile days with hills will teach you more about your stamina than one 20-mile push.
• Include rough ground. Footpaths with roots, loose stone and mud are slower and more tiring than smooth trail, so seek them out on training walks.

Set Honest Daily Distances

On the coast path, two miles an hour is a realistic average for most walkers once you account for ascent, stiles, gates, photo stops and the occasional wrong turn. Three miles an hour is achievable only on the rare flat sections and on the best-surfaced stretches.

A sensible early schedule is 8 to 12 miles a day. Fit, experienced walkers with light packs can push to 15 or 16, but doing that on day one is a reliable way to wreck your feet and your enthusiasm. Add ascent to your calculations, not just distance: a 10-mile day with 600 metres of climbing is a much bigger proposition than a 12-mile day with 200 metres.

Build in a short day every fourth or fifth day. Use it to rest, dry kit, resupply and let any niggles settle. Plan your overnight stops around villages with accommodation, pubs and shops rather than aiming for a tidy round number.

Water, Food and Fuel

Water points are one of the genuine challenges. Some stretches run for hours with no tap, no shop and no stream you'd want to drink from, particularly on the more remote headlands in Cornwall and north Devon.

• Carry at least two litres between refill opportunities, and more in hot weather.
• Refill whenever you can. Village taps, pub toilets, cafés, campsites and churchyards are all fair game if you ask politely.
• Carry a backup treatment. Purification tablets or a filter give you options if a planned source turns out to be dry or dubious.
• Eat little and often. Aim for 200 to 300 calories an hour on the move — oatcakes, nuts, flapjack, dried fruit, sandwiches from the village shop.
• Plan a hot meal. A pub dinner or a rehydrated meal at camp makes a real difference to how you feel the next morning.

Kit, Feet and Weather

Keep your pack weight sensible — 10 to 12 kilograms including water and food is a good target for a week. Every extra kilo is felt on the tenth climb of the day.

• Footwear: either well-broken-in boots or grippy trail shoes, depending on ankle strength and pack weight. Whichever you choose, wear them on training walks, not straight out of the box.
• Blister kit: tape, dressings and a spare pair of socks. Treat hot spots the moment you feel them.
• Layers and waterproofs: coastal weather changes fast. Windproof and waterproof outer layers are non-negotiable, even in July.
• Navigation: paper map and compass alongside any phone app, plus a power bank. Signal is patchy and batteries die.
• Trekking poles: genuinely useful on the descents, which are harder on the body than the climbs.

Check tide times before you set out, especially where the path crosses estuaries such as the Erme, the Avon and the Helford, and where seasonal ferries are the only way across. A missed crossing can add miles you hadn't planned for. Finally, tell someone your route and expected finish times each day — mobile coverage comes and goes, and a text from the next village is a small habit that keeps you safe.
