There's a version of hiking that involves a thermos of tea, a gentle gradient, and a pub at the end. And there's another version that leaves your legs properly wrecked for three days and gives you a view you genuinely can't stop thinking about. Both are valid. But if you want the second kind with any reliability, the training actually matters — and so does how you choose a tour.
Britain has more hiking terrain than most people realise. England and Wales alone have around 140,000 miles of public footpaths, and Scotland adds vast open access land on top of that. The variety is extraordinary — from the flat salt marshes of Norfolk to the technical ridgelines of the Cuillin on Skye. The question isn't whether there's somewhere good to walk. It's whether you're physically ready for it, and whether you need a guide to get the most out of it.
Why hiking training gets underestimated
Most people underestimate how specific hiking fitness is. Running helps. Cycling helps. But neither fully prepares your legs for sustained descents on uneven ground with a loaded pack — which is the thing that quietly destroys people's knees on multi-day routes. The muscles that take the strain going downhill, particularly the quads and the stabilisers around the knee, need specific work that flat cardio simply doesn't provide.
Single-leg exercises are the most useful thing most hikers aren't doing. Lunges, step-ups, and split squats build the unilateral leg strength that makes a difference on steep ground, where your legs work independently rather than together. For anyone preparing for a serious hiking tour — something like a multi-day section of the Pennine Way or a week in the Scottish Highlands — six weeks of progressive training makes a significant difference to how you feel on day three.
The other element people skip is loaded walking. Carrying a 10kg rucksack changes everything: your gait, your pace, the pressure on your feet and hips. If your hiking tour involves carrying kit and you've done all your preparation without a pack, you'll feel it. Simple fix: start adding weight to your weekend walks four to six weeks out from the trip and build from there.
What to look for in a guided hiking tour
The Mountain Leader (ML) qualification, awarded through Mountain Training, is the recognised standard for leading groups in the hills and mountains of Britain and Ireland. It covers navigation, group management, emergency procedures, and route planning across all mountain and moorland terrain, making it a key part of professional hiking training. When you're booking a guided hiking tour, checking that your guide holds this qualification — or the Walking Group Leader award for lower-level routes — is the simplest way to filter out the underqualified.
Group size matters more than most people consider when booking. Smaller groups — typically six to eight people — give the guide the flexibility to actually adjust the pace and route to conditions, rather than just keeping the column moving. Some of the best-guided hiking experiences in the UK run with as few as four to six participants, which makes the whole thing feel more like going out with a very knowledgeable friend than joining an organised march.
Three hiking tours worth knowing about
The Cairngorms in Scotland are criminally underused by English hikers. Glenmore Lodge — Scotland's national outdoor training centre, based in Aviemore — runs guided hiking programmes in the area, and the plateau itself, at over 1,000 metres, offers a genuinely remote feel within a few hours of the central belt. The Lairig Ghru, a 30km mountain pass cutting through the heart of the range, is one of the great day routes in Britain.
In Wales, the Brecon Beacons Waterfall Country in the south of the national park is worth a guided tour specifically because the best routes — particularly those involving the four falls walk around Pont Melin-fach — involve some navigation that rewards local knowledge. The waterfalls here include Sgwd yr Eira, where the path runs directly behind the cascade. It's the kind of thing that's hard to stumble on without guidance.
For something more accessible, the North York Moors offer superb walking on heather moorland above deeply cut dales, with the added interest of the area's industrial history — ironstone, alum, and jet mining all left their mark on the landscape, and a good guide will tell you why the valleys look the way they do.
