How to Train for K2 Base Camp Trek

Disclaimer: Training for K2 Base Camp is a big deal, something to take seriously if you want your adventure in the Karakorams to be a success. The good news is, everything you need to make your K2 Base Camp trek work is right here on this page.

Anyway, you’ve set your sights on trekking to K2 Base Camp?

First things first, amazing choice! This is one of the most breathtaking (literally…more on that in a mo) and challenging treks on the planet.

But let’s be real for a moment, this isn’t your average Sunday stroll. No walk in the park either. The trek to K2 Base Camp is tough, demanding, and requires serious preparation.

If you don’t know how to train for K2 Base Camp properly, you’ll be cursing yourself somewhere around the Baltoro Glacier. So let’s get you in top shape to make this adventure unforgettable (for the right reasons)…

How Hard Is the Trek to K2 Base Camp?

In one word? Pretty brutal. Okay, that’s two words, but you catch our drift.

The trek to K2 Base Camp is around 90 miles (145 km) round trip, with long days of hiking, steep ascents, and unpredictable terrain.

Unlike Everest Base Camp, there are no cosy tea houses, just raw, rugged wilderness. It’s delicious. You’ll be crossing glaciers, navigating rocky trails, and dealing with extreme weather, with the trek becoming what we call ‘technical’ in places.

Oh, and did we mention the altitude? At 5,150m (16,900ft), the air is thin, and every step feels twice as hard.

And that’s why you must prepare for K2 Base Camp like, well, like an athlete. You need stamina, strength, and mental resilience. Shall we get on with it then? Let’s dive into exactly how you should train for K2 Base Camp.

Understanding Altitude Sickness

Quickly before we get into the actual training for K2 Base Camp, let’s talk about altitude sickness.

It’s a real threat and can hit even the fittest trekkers. The higher you go, the lower the oxygen levels, and your body needs time to adjust. Symptoms can range from headaches and nausea to full-blown Acute Mountain Sickness (AMS), which can be dangerous.

How to reduce your risk of altitude sickness:

Train for K2 Base Camp with cardio and endurance workouts to improve oxygen efficiency.
Acclimatise properly during the trek — go slow, take rest days, and listen to your body.
Hydrate like crazy — dehydration makes altitude sickness worse.
Consider using Diamox (but consult a doctor first).

You’ll find out plenty more about altitude sickness (and how to prevent it) in our guide here.

When to Start Training for K2 Base Camp

If you’re serious about this trek, start training at least 4–6 months in advance. If you’re already fit, 3 months might be enough, but the earlier, the better. Ideally, you’ll want to train at least 4-5 times a week, mixing cardio, strength, and endurance workouts. And if you can fit in at least one altitude session per week, even better.

Training Plan for K2 Base Camp

Train on Mountains (Or Hills!)

Hiking on actual mountains is the best way to prepare for K2 Base Camp. Aim to do at least one long hike per week, ideally in a mountainous area. If you don’t have mountains nearby, find the steepest hills or use a treadmill at max incline.

You can also get seriously funky with a visit to The Altitude Centre [OPEN IN NEW TAB] in London, where you can take Intermittent Hypoxic Exposure sessions – the quickest way to adapt to low oxygen. Find out more about training for altitude trekking in the UK HERE.

Key points when you’re training for K2 Base Camp in the UK:

Carry a weighted backpack (start light and increase gradually to 10-15kg).
Train in different weather conditions — K2 Base Camp can throw anything at you.
Focus on multi-day hikes to get used to trekking while fatigued.

Practice Hikes with Full Gear

Get used to hiking in the same boots and backpack you’ll use for the trek. Break everything in — blisters at 4,000m are not fun. Try multi-day hikes with back-to-back long days and see how you get on.

Remember, on your K2 Base Camp trek, it’s day after day of long, strenuous hiking at high altitudes – time to get used to it!

Endurance Training: Build Stamina

The trek to K2 Base Camp requires long days of walking, often 6-8 hours at a time. You need endurance. So how do you build that up?

Best endurance exercises:

Long hikes (6+ hours with a pack)
Running (trail running is best!)
Cycling (great for leg endurance)
Swimming (builds lung capacity for high altitudes)

Full-Body Strength Workouts

Strength is crucial to avoid injury and keep you going day after day. Focus on your legs, core, and shoulders — you’ll be carrying a heavy pack and navigating uneven ground.

Best strength exercises:

Squats and lunges (build leg power)
Step-ups with a weighted pack (mimic hiking uphill)
Deadlifts and core exercises (stabilise your body)
Shoulder and back training (for your backpack)

Tip: Why not hire a personal trainer for the first month of your training for K2 Base Camp, so you can get a great hold on technique, get into a rhythm and go from there?

Mental Toughness: Train Your Mind

The K2 Base Camp trek is as much mental as it is physical. Some days will be exhausting, cold, and relentless. Build mental resilience by pushing yourself on tough training days and embracing discomfort. You’ll love it. Well, hopefully.
