Three Peaks Challenge: Everything You Need to Know

The Three Peaks Challenge isn’t just a hike – it’s an unforgettable adventure across the UK’s most stunning landscapes. Scaling Ben Nevis, Scafell Pike, and Snowdon in one continuous push tests your grit, stamina, and determination. 

It’s a battle against steep ascents, unpredictable weather, and the relentless ticking of the clock. 

But for those who conquer it, the reward is more than breathtaking views; it’s a sense of triumph and connection with nature’s raw beauty. 

Whether you’re chasing personal growth or a group accomplishment, this guide equips you with everything you need to tackle the UK’s ultimate mountain challenge.

What is the Three Peaks Challenge?

The Three Peaks Challenge is a popular hiking endurance test in the UK. It involves climbing the highest peaks in Scotland, England, and Wales – Ben Nevis, Scafell Pike, and Snowdon – within a set time frame. 

Participants typically aim to complete the challenge in 24 hours, though variations include a 48-hour or 3-day schedule.

The challenge includes around 23 miles (37 km) of hiking and a total ascent of 10,052 feet (3,064 meters). This is equivalent to climbing Mount Snowdon three times back-to-back. 

On top of this, there’s also a driving component, as the mountains are spread over 462 miles. This requires careful planning, efficient transitions, and a good level of fitness.

What are the Three Highest Peaks in the UK?

The Three Peaks Challenge focuses on the tallest mountains in each country of mainland Britain. These are:

• • Ben Nevis in Scotland, standing at 1,345 meters (4,413 feet).

• • Scafell Pike in England, at 978 meters (3,209 feet).

• • Snowdon in Wales, at 1,085 meters (3,560 feet).

Contrary to some misconceptions, these are not the three highest peaks in the UK overall. Many higher mountains exist in Scotland, but these peaks represent the tallest in each country.

Ben Nevis

• • Height: 1,345 meters (4,413 feet)

• • Hike Distance: Approximately 10.5 miles (17 km) round trip

Ben Nevis is the tallest mountain in the UK and serves as the first or final peak in the challenge, depending on the direction chosen. 

Located in the Grampian Mountain range near Fort William, it offers a demanding but rewarding ascent.

The most common route, the Mountain Track (or Tourist Path), is well-trodden but steep. It includes a mix of rocky paths, zigzag sections, and a final stretch often shrouded in mist. 

The summit is stark and dramatic, with a weathered plateau and a memorial marking the highest point. On a clear day, views extend over the Highlands and beyond, making the climb unforgettable.

Ben Nevis’s volcanic origins are evident in its rugged terrain. Despite its challenges, the trail is accessible to well-prepared walkers with good stamina. 

Weather conditions can change rapidly, so proper gear and navigation skills are essential. It’s always a good idea to have some experience of hiking in Scotland before you tackle Ben Nevis.

Scafell Pike

• • Height: 978 meters (3,209 feet)

• • Hike Distance: Approximately 6 miles (10 km) round trip

Scafell Pike is England’s highest mountain and a central part of the Three Peaks Challenge. 

Located in the Lake District National Park, it’s renowned for its steep, rocky terrain and challenging navigation. The most common route begins from Wasdale Head, which is relatively short but includes a gruelling ascent.

The landscape is striking, with rugged slopes, scattered boulders, and views of surrounding peaks and lakes. The climb can feel relentless, with little respite from the steep gradient. 

The summit is marked by a large cairn and offers breathtaking views when weather permits. However, visibility can be limited by cloud cover, making a map and compass or GPS vital.

Despite being the shortest climb of the three, Scafell Pike often surprises challengers with its difficulty. The rocky paths require good footwear and sure-footedness. 

Its remote beauty and the sense of achievement at reaching the top make it a favourite among hikers.

Snowdon

• • Height: 1,085 meters (3,560 feet)

• • Hike Distance: Approximately 7 miles (11 km) round trip via the Llanberis Path

Snowdon, or Yr Wyddfa in Welsh, is Wales’s highest peak and a fitting finale to the Three Peaks Challenge. 

Situated in Snowdonia National Park, it boasts dramatic scenery and diverse wildlife. Its popularity is reflected in the range of trails available, but the Llanberis Path is the most commonly used for the challenge due to its moderate gradient.

The path winds steadily upward, passing through picturesque landscapes, including grassy slopes, rocky outcrops, and the famous Halfway House. 

The summit features a café (open seasonally) and a stone marker at the peak. On clear days, the views are truly spectacular, encompassing Snowdonia, the Irish Sea, and even parts of Ireland.

Snowdon’s varied routes cater to all levels, but the mountain’s unpredictable weather and long ascent demand preparation. 

Completing Snowdon as the final peak of the challenge often feels both exhausting and exhilarating, marking the end of an incredible adventure.

Three Peaks Challenge Itinerary and Route

The Three Peaks Challenge follows a specific order and includes significant hiking and driving between mountains. Most participants choose one of two common itineraries: starting with Ben Nevis and heading south, or beginning with Snowdon and heading north. 

The former is more popular due to logistics and sunrise alignment.

• • Ben Nevis (Scotland): Begin the ascent early, typically around 5:00–7:00 AM. The Mountain Track is the most common route and takes about 5–7 hours for the round trip.

• • Scafell Pike (England): After a long drive (around 6 hours), tackle Scafell Pike, often starting in the evening or late at night. The Wasdale Head route is the shortest, requiring about 3–5 hours.

• • Snowdon (Wales): Drive approximately 4–5 hours to reach Snowdon for the final climb, often in the early hours of the next day. The Llanberis Path is typically used, taking 4–6 hours.

Efficiency is key. Teams must manage rest breaks, food, and transitions quickly. Many participants hire a driver to maximise rest during travel.

How Hard is the Three Peaks Challenge?

The Three Peaks Challenge is physically and mentally demanding. Completing three mountain climbs, totalling 23 miles with 10,052 feet of ascent, within 24 hours is a serious undertaking. 

Fatigue from hiking combines with limited sleep and lengthy drives, amplifying the difficulty.

Each mountain presents unique challenges. Ben Nevis’s long ascent, Scafell Pike’s steep and rocky terrain, and Snowdon’s final push all require stamina and strength. Descents can be especially punishing on knees and legs.

Weather, darkness, and time pressure can take a toll. Hiking at night or in poor visibility demands focus. Staying motivated through physical exhaustion is crucial.

Preparation is essential. Training, proper gear, and a clear understanding of the challenge help participants succeed.

When is the Best Time to do the Three Peaks Challenge?

The best time for the Three Peaks Challenge is between late spring and early autumn, typically May to September. These months offer longer daylight hours and more favourable weather conditions.

In summer, daylight extends past 9:00 PM, reducing the need for nighttime navigation. Trails are generally safer, with less risk of ice or snow. Temperatures are milder, though summer storms can still occur.

Winter months bring short days, requiring more hiking in the dark. Snow and ice make paths treacherous, and adverse weather increases risks. Autumn and early spring can be unpredictable, with heavy rain and strong winds.

Check weather forecasts for all three mountains before setting out. Choose a clear window to maximise safety and enjoyment.

How to Train for the Three Peaks Challenge

Training is crucial to build the stamina and strength needed for the Three Peaks Challenge. A focused program over 8–12 weeks can prepare most participants.

• • Cardio Training: Build endurance with activities like running, cycling, or swimming. Aim for at least 3 sessions a week, increasing duration and intensity gradually.

• • Hill Walking: Practice on local hills or smaller mountains. Replicating steep ascents and descents strengthens legs and improves familiarity with uneven terrain. 

• • Strength Training: Incorporate exercises like squats, lunges, and deadlifts to build lower body strength. Core exercises help with stability on rugged trails.

• • Long Walks: Build up to back-to-back long walks or hikes to simulate the challenge. Carrying a loaded backpack adds realism. Check out our list of the best walking trails in the UK for some excellent training paths.

Rest and recovery are vital. Gradually increase your workload, and taper intensity in the final week before the challenge.

How to Take Part in the National Three Peaks Challenge

There are two main ways to participate in the National Three Peaks Challenge: organising your own group or joining a professionally guided event.

• • Self-Organised Groups: This is often more cost-effective but requires careful planning. You’ll need to arrange transport, plan routes, and ensure safety measures. Registering your challenge with a reputable body can provide guidance and certificates for completion.

• • Professionally Guided Events: These are ideal for first-timers or larger groups. Organisers handle logistics, including drivers, routes, and safety support. They also offer expert guidance, increasing the chances of success.

Regardless of your choice, ensure everyone in your group is fit, prepared, and equipped. Familiarise yourself with the rules and guidelines for safe, responsible participation.
