NATIONAL 3 PEAKS - TRAINING WHAT ACTUALLY WORKS (2026 GUIDE)

MOST PEOPLE DON'T FAIL THE NATIONAL 3 PEAKS BECAUSE THEY'RE UNFIT...

They fail because they train the wrong way.


They hit the gym.
They do a few runs.
They think that’s enough.

Then they get onto the mountains and realise very quickly…


👉 This is a completely different game.

WHAT THE CHALLENGE ACTUALLY DEMANDS

The National 3 Peaks is not just a hike — it’s a 24-hour endurance event, testing how you cope with very little sleep, 10/11 hours travelling and eating enough calories to sink a ship.


You’re taking on:

  • Ben Nevis
  • Scafell Pike
  • Snowdon

All within 24 hours.

That means:

  • Around 25 miles of hiking
  • Over 3,000m of ascent
  • Roughly 12–13 hours on your feet
  • Burning between 5/6000 calories
  • Plus 10+ hours of driving in between

And the biggest factor?

👉 Fatigue.

Not just physical — mental and emotionally.


WHY BEING "FIT" ISN'T ENOUGH

You are more than able to run 10k and still struggle on the challenge.

Because this challenge isn’t about speed.

It’s about:

  • Long days on your feet
  • Uneven terrain
  • Climbing when your legs are already tired
  • Moving when you’d rather stop
  • Most importantly not giving up when every part of you is saying you cannot do, because you can!

👉 It’s about durability, stubbornness not just the fitness.


WHAT ACTUALLY WORKS (THE RIGHT WAY TO TRAIN)

1. TIME ON YOUR FEET (NON NEGOTIABLE)

This is the biggest one.

You need to get used to:

  • Walking for hours
  • Being on your feet when tired
  • Managing pace over long periods

Start with:

  • 2–3 hour hikes
  • Build up to 5–7 hour days


2. BACK TO BACK TRAINING DAYS

The challenge doesn’t give you recovery time — so neither should your training.

Example:

  • Saturday: long hike
  • Sunday: another hike (even when tired)

👉 This is where real progress happens.


3. STRENGTH TRAINING (THIS IS YOUR SECRET WEAPON)

Focus on:

  • Legs (quads, glutes, calves)
  • Core (for stability)

Simple works:

  • Squats
  • Lunges
  • Step-ups (gold standard for mountains)
  • Loaded carries

👉 Strong legs = less fatigue = higher chance of success


4. TRAIN ON UNEVEN TERRAIN

Treadmills won’t prepare you for this.

You need:

  • Hills
  • Trails
  • Rocky paths

Because that’s what breaks people.


5. PRACTICE FUELING AND HYDRATION

This is where a lot of people fall apart.

You should be testing:

  • Snacks - a lot of people think that protein bars will help, on a challenge they won't
  • Hydration - electrolytes, test them plenty of times before, a lot of people they go straight through! Not pleasant and the last thing you want to happen an hour in on Ben Nevis haha.  Your not going to find a toilet that's for sure
  • What your body tolerates under fatigue

👉 Don’t figure this out on the mountain.


WHAT MOST PEOPLE GET WRONG

  • Not enough time on feet
  • No back-to-back training
  • Overestimating gym fitness
  • Ignoring nutrition
  • Leaving it too late

And the big one…

👉 Thinking they’ll “push through it on the day”

That’s where people come unstuck.


HOW LONG DO YOU NEED TO TRAIN?

Ideally:
👉 
12–16 weeks

That gives you time to:

  • Build gradually
  • Avoid injury
  • Actually feel ready (not just hopeful and wishful thinking)


THE HONEST TRUTH

This is a tough challenge.

But it’s absolutely achievable…

👉 If you prepare properly.

Do that — and it becomes one of the most rewarding things you’ll ever do.

Skip it — and it can be a long, miserable, hard 24 hours.

There’s something transformative about standing on a summit, breathless and sweat-soaked, gasing out over ridgelines and valleys below. It’s not just the view that takes your breath away—it’s the emotional clarity that comes from the climb itself. At Chasing Summits , we know first-hand how mountains do more than just challenge the body; they awaken the mind and strengthen the soul. Physical challenges—particularly those faced in the great outdoors—have a powerful way of building emotional intelligence. The Mountain as a Mirror When you're on a tough ascent—say up Scafell Pike , England’s highest peak, or navigating the awe-inspiring route to Snowdon via Crib Goch —your true self shows up. Fatigue strips away the layers. Every step forces you to face your limits, your thoughts, your inner dialogue. There’s no signal, no distraction—just you, your team, and the trail. This intensity encourages emotional awareness . You learn to notice how fear, frustration, and doubt creep in. More importantly, you learn to manage them. You become familiar with your internal landscape just as much as the physical one surrounding you. This is emotional intelligence in action - recognising what you feel, understanding why, and managing your response to keep moving forward. Resilience and Regulation Climbing isn’t easy. Neither is life. But mountains teach us resilience like nothing else. A day trek in the Lake District , for instance, can be unpredictable—weather can turn, paths can vanish, and plans can shift. It’s in these moments that emotional regulation becomes crucial. You learn to breathe through the panic, to make calm decisions, and to re-centre yourself under pressure. These are the very same skills that help us handle stress in everyday life—at work, in relationships, and in our own mental health battles. Empathy and Team Spirit One of the most beautiful aspects of expedition life is the people you meet along the way. Whether you're on a private guided hike with us or joining one of our open group adventures , you’re not climbing alone. Mountains create a shared struggle, a collective experience that binds strangers together. Encouraging someone who's ready to give up, or accepting support when you're the one struggling, naturally fosters empathy. You develop patience, compassion, and the ability to read the emotional needs of others. These are key pillars of emotional intelligence, and they flourish in the raw, honest environment of the trail. Mindfulness in Motion For many of us, including our founder Nic, the mountains offer peace. The mind goes quiet. The noise of modern life fades away and all that remains is the rhythmic crunch of boots on rock and the steady beat of your heart. It’s a form of mindfulness—present, grounded, and connected. Take our Ben Nevis Challenge , for instance. As the UK’s highest mountain, it requires focus, grit, and respect. But it also gives you a chance to reconnect with yourself in a way few experiences can. You leave the peak changed—stronger, calmer, more self-aware. More Than a Climb At Chasing Summits, we don’t just guide you up a mountain—we guide you into a deeper connection with yourself. Whether it’s a short day hike or a more demanding expedition like the Welsh 3000s Challenge , every route is an opportunity to build confidence, self-awareness, and emotional strength. The next time you find yourself craving clarity or feeling overwhelmed by life’s chaos, consider heading to the hills. Your body will feel the burn, yes—but your mind and heart will thank you for it.  Ready to start your journey within?
