What Fitness for an Arctic Expedition? Your Guide
A loaded sledge does not care how good you were at the gym in January. It cares whether you can keep moving when the snow is soft, the temperature is low and there are still several kilometres between you and camp. If you are asking what fitness for an Arctic expedition is needed, the encouraging answer is this: you do not need to be an elite athlete. You do need to arrive prepared to work steadily, recover well and look after yourself in a demanding environment.
Arctic fitness is practical fitness. It is the ability to walk, pull, carry, balance, layer up, eat and keep going day after day. On a guided trip, your leaders will bring experience, route knowledge and clear support. Your training gives you more capacity to enjoy the journey, contribute to the team and take in the wild places you have travelled so far to see.
What fitness for an Arctic expedition really means
The right preparation depends on the expedition. A husky sledding journey, for example, asks for balance, mobility and the confidence to be active outdoors for long periods. A pulk expedition, where you pull your own equipment in a sledge, puts greater emphasis on leg strength, cardiovascular endurance and resilient shoulders and hips. Snowshoeing, skiing and winter camping each have their own demands.
The common thread is sustained effort rather than speed. You may be moving for four to seven hours in a day, with breaks to drink, eat, adjust clothing and enjoy the landscape. The terrain may be rolling rather than mountainous, but snow creates resistance. Cold also makes ordinary jobs more tiring: fastening boots, handling kit with gloves on, setting up camp and keeping warm all take energy.
A useful benchmark is being able to complete a full day of hill walking with a rucksack, then feel capable of doing something similar again the following day. You should expect to be pleasantly tired, not utterly spent. Expedition life rewards people who can settle into a rhythm and manage their effort rather than those who charge ahead early.
Build an engine for long, steady days
Your aerobic base is the foundation. Walking is often the best place to start because it closely matches how many Arctic journeys feel: time on your feet, variable ground and a consistent, controllable pace. Begin with regular brisk walks and gradually increase both the duration and the hills.
If you live near hills, use them. If you do not, stairs, a treadmill on an incline, cycling and rowing are all valuable ways to build fitness without relying on perfect terrain. Aim for sessions where you can speak in short sentences but would not want to give a speech. This is the sort of effort that develops the stamina needed for sustained travel.
One longer session each week is especially worthwhile. Start at a level that feels realistic, then add time slowly. For someone new to training, that might mean building from a 60-minute walk to three or four hours over several weeks. For an experienced hillwalker, it may mean adding back-to-back days, more ascent or a heavier pack.
There is a trade-off here. Hard intervals can improve fitness quickly, but they are not the main event for most Arctic trips. Too much high-intensity training can leave you sore, fatigued or injured. A reliable base built through consistent walking, cycling, skiing or running will serve you better than a short burst of heroic sessions.
Train strength for pulling, carrying and camp life
Strength training makes winter travel feel more controlled. It helps when you are hauling a pulk, stepping through uneven snow, lifting a duffel bag or getting up from the ground after a break. It also supports your joints when tiredness begins to affect your movement.
Focus on simple, repeatable movements two or three times a week. Squats or step-ups build leg strength for climbs and soft snow. Lunges help with single-leg stability. Deadlifts or hip hinges strengthen the posterior chain, which is useful for carrying and pulling. Rows, presses and loaded carries prepare your upper body for poles, sledges and everyday camp tasks.
You do not need a complicated programme or a room full of equipment. A rucksack, resistance band, a pair of dumbbells and a sturdy step can take you a long way. Start light enough to move well, then gradually increase the load or repetitions. Good technique matters more than lifting heavy for the sake of it.
Core training is useful too, but think beyond endless sit-ups. Planks, side planks, bird dogs and controlled carries teach your trunk to resist twisting and collapsing while your arms and legs work. That stability can make a noticeable difference when traversing uneven snow or managing a pull harness.
Practise with the kit you will use
The most expedition-specific training is done outdoors, with the equipment you will carry or wear. Break in your walking boots well before departure. Test your socks, gloves and layers during wet, windy and cold British days. Learn whether your pack rubs after two hours, whether your jacket is too warm on the move and whether you can reach snacks without taking everything off.
For a trip involving a rucksack, build load gradually. Begin with a light pack and increase the weight only when your feet, knees and shoulders are coping comfortably. There is no prize for loading it to expedition weight on your first outing. For a pulk-based expedition, your operator may give specific guidance on hauling practice, but hill walking with a pack, step-ups and strength work are excellent preparation if you do not have access to a sledge.
Bad weather is not a reason to stay indoors every time. A sensible walk in rain, wind or cold is a chance to practise pacing, food stops and layer management. Stay safe, choose suitable routes and avoid severe conditions, but do not wait for perfect blue skies. Arctic travel is more enjoyable when you already trust your ability to stay comfortable through changing weather.
Build the skills that protect your energy
Fitness is not only physical. People often tire quickly because they are dehydrated, under-fuelled, too hot, too cold or moving at the wrong pace. Learning to manage these basics is part of becoming expedition-ready.
Eat regularly on longer training days and notice what sits well with you while walking. Drink before you feel desperate for it. Practise putting on and taking off layers before you are sweating or shivering. Keep easy-access snacks close at hand. Small decisions made early save a surprising amount of energy later.
It is also worth training your mindset. Arctic environments can feel vast, quiet and unfamiliar. There may be early starts, shared camp routines and moments when the conditions make a simple task slow. Approach this as part of the experience, not as a test you must endure alone. A good expedition team checks in, shares the work and keeps perspective when the day is tough.
A realistic 10-week Arctic fitness plan
Ten weeks is enough time to make meaningful progress if you train consistently. If you have more time, build more gradually. If your departure is closer, focus on regular movement, sensible strength work and avoiding last-minute overload.
Weeks 1 to 3: Create the habit
Complete three aerobic sessions each week, including one longer walk. Add two full-body strength sessions with a focus on legs, hips, back and core. Keep the effort manageable. You are building a routine your body can recover from, not proving anything in week one.
Weeks 4 to 7: Add time and terrain
Lengthen the weekly walk, introduce hills or stair work and begin carrying a light pack if appropriate. Keep two strength sessions, increasing resistance gradually. Add one back-to-back weekend every fortnight, such as a longer Saturday walk followed by an easier but still active Sunday.
Weeks 8 to 10: Make it expedition-specific
Complete a few longer days in the boots, pack and clothing you intend to use. Practise eating and drinking while moving. Maintain strength, but reduce the temptation to chase personal bests. In the final week, ease back slightly so you arrive rested, mobile and keen to go.
Know when to adapt the plan
An old knee issue, a recent injury, asthma, heart concerns or any condition that affects exercise deserves proper attention before you travel. Speak with a qualified health professional where needed, and be honest with your expedition provider about anything that may affect your participation. Adjusting a plan early is sensible preparation, not a weakness.
The same applies if you are new to walking or strength training. Start where you are. Consistency beats intensity, and a programme that fits around work and family is far more useful than one abandoned after ten days. Snow and Paddles adventures are guided, but your preparation is still a commitment to yourself and the people sharing the journey with you.
Train for the moments you want to remember: the first wide view over frozen ground, the quiet pull of the sledge across fresh snow, the warmth of camp after a full day outside. Build a body that can stay present for those moments, and the Arctic will feel less like something to survive and more like a place you truly get to experience.
