A Twelve-Week Training Plan for a Trekking Journey
Three months is enough time to arrive genuinely ready for a walking journey — if those weeks are used well. Here is a clear, progressive plan, week by week, that turns ordinary fitness into trail-ready fitness.
If your journey includes real walking days — the Patagonian trails of Andes to Antarctica, the high passes of The Silk Road Reborn, the long ridges of The Long Way East — the single most useful thing you can do before departure is to train for twelve weeks. Not heroically, not daily, but consistently. Three to four sessions a week, building gradually, is enough to change how the journey feels.
The plan below moves through three phases of four weeks each: a base phase to build the aerobic engine, a build phase to add load and hills, and a peak-and-taper phase that rehearses the real thing and then lets you arrive fresh. Before you begin any new exercise programme, particularly if you are over fifty or have not trained in a while, have a conversation with your doctor.
Weeks 1 to 4 — building the base
The first month is about frequency, not intensity. The goal is simply to teach your body to move comfortably for an hour at a time, several times a week. Aim for three walks of forty-five to sixty minutes on varied ground, plus one longer walk at the weekend that grows from ninety minutes to two hours by week four. Keep the pace conversational — you should be able to talk in full sentences throughout.
Add two short strength sessions of twenty minutes, focused on the legs and core: sit-to-stand squats, step-ups onto a low bench, calf raises, and a plank. These need no gym. By the end of week four, a two-hour walk should leave you pleasantly tired rather than wrecked. If it does not, repeat week four before moving on — the plan is a guide, not a deadline.
Weeks 5 to 8 — adding hills and load
Now the walking becomes more specific. Replace one flat walk each week with a hill session: find the longest sustained climb near you and walk up and down it, repeating until you have done sixty to seventy-five minutes. Hills are non-negotiable preparation, because no amount of flat walking trains the body for the relentless up-and-down of a real trail.
Begin walking with the daypack you intend to carry, loaded to roughly the weight you will actually carry on the journey — usually five to eight kilograms of water, layers and camera. Start light and add a kilogram every week or two. Your weekend walk should now reach three to four hours, on the most varied terrain you can reach. Keep the two strength sessions, but increase the difficulty: deeper squats, higher step-ups, single-leg calf raises.
Weeks 9 to 11 — the peak
These are the most demanding weeks, and they exist to rehearse the journey rather than to set records. The centrepiece is back-to-back long days: a walk of four to five hours on a Saturday, followed by a walk of two to three hours on the Sunday, on tired legs. This is the truest preparation there is, because escorted journeys ask you to walk well on consecutive days, not to perform once.
Carry your loaded pack on every long walk now. Seek out descents in particular and practise walking down them with control, because downhill is what most often surprises and aches the untrained traveller. Keep one shorter midweek walk and one strength session, but listen closely to your body — peak weeks are where overuse niggles appear, and a small ache attended to now is a problem avoided later.
Week 12 — the taper
In the final week before you travel, do less. This feels counter-intuitive, but tapering is how the work of the previous eleven weeks is banked. Cut your walking volume by roughly half, keep the intensity gentle, and drop the strength sessions to one easy session early in the week or none at all.
The aim is to arrive at the airport rested, not depleted, with legs that feel springy rather than heavy. Use the freed-up time to break in footwear if you have not already, sort your layering system, and sleep well. Fitness is not lost in a quiet week — it is consolidated.
Making the plan fit your life
Few people follow a training plan perfectly, and they do not need to. If you miss a week to illness or travel, do not try to cram it back; simply rejoin where you left off, even if that means repeating a phase and pushing your start date earlier. Consistency across twelve weeks matters far more than any single session.
If you already walk regularly, you may compress the base phase; if you are starting from very little, give yourself sixteen weeks rather than twelve. The structure — base, build, peak, taper — holds at any length. What it reliably produces is a traveller who spends the journey looking at the landscape rather than at their own feet.
Quick answers
What if I only have eight weeks before departure?
Eight weeks is still very worthwhile. Shorten each phase: two weeks of base, three of build, two of peak and one of taper. You will not arrive as comprehensively prepared as with twelve weeks, but the difference between eight weeks of structured training and none at all is enormous. The priorities, if time is short, are hill walking and back-to-back long days.
Do I need a gym for the strength sessions?
No. Every strength exercise in this plan — squats, step-ups, calf raises, planks — can be done at home using your own body weight, a staircase and a sturdy chair. A gym is convenient and offers progression with weights, but it is in no way required. Walking on hills with a loaded pack is itself excellent strength training for the legs.
How do I know if I am training too hard?
Persistent fatigue that does not lift with a rest day, sleep that worsens rather than improves, a resting heart rate that climbs, or joint pain that sharpens during exercise are all signs to ease off. Training should leave you tired then recovered, not steadily more depleted. When in doubt, take an extra rest day — under-training slightly is far safer than over-training.
