(The Gear Loop) - The longer days and (hopefully) balmy weather of a UK summer is one of the best times to complete the National Three Peaks challenge, which sees competitors aim to summit Ben Nevis, Scafell Pike and Snowdon in a time window of just 24 hours.

It requires a good level of fitness and a sharp mind for logistics, but it can be one of the most rewarding things fans of walking and hiking can do. We asked James Forrest, one of the fastest men to complete all three peaks (walking to each destination in between), for his insight into the best way to success.


"It was the adventure of a lifetime - and the longest continuous walk I’d ever completed. In August 2021 I walked 17 marathons in 17 days to complete a 492-mile journey on foot, climbing Ben Nevis, Scafell Pike and Snowdon - and hiking every mile in-between them... in just 16 days, 15 hours and 39 minutes. It was a new record for a self-supported, solo walk of the National Three Peaks, beating the previous best of 19 days, 18 hours and 35 minutes by Tina Page. But why on earth did I do it?" 

Long, arduous journeys aren’t for everyone (you’ll certainly experience some atrocious weather, feel utterly exhausted and suffer from excruciating blisters!), but personally, I get a real endorphin rush from the exercise and a buzz from venturing outside my comfort zone. I absolutely love challenging myself, pushing my boundaries and seeing what I can achieve in the great outdoors. There’s a calming aspect, too. I find the simple process of walking incredibly therapeutic - it works wonders for my mental well-being and brings contentment to my life.

You don’t have to take on such a hardcore hike, however, to complete the National Three Peaks challenge. The usual approach is to drive between the peaks, aiming to summit all three mountains in under 24 hours. It is one of the UK’s most iconic and longest-standing mountain challenges. Here’s everything you need to know about it. 

If you want to brush up your knowledge of the peaks involved, check out our in-depth guides to Ben Nevis, Snowdon and Scafell Pike.

What is the National Three Peaks challenge?

The National Three Peaks Challenge does what it says on the tin. The goal is to climb the highest peaks of Scotland, England and Wales, often within 24 hours. The three peaks are:

  • Ben Nevis (1,345m) – Scotland’s highest mountain
  • Scafell Pike (978m) – England’s highest mountain
  • Snowdon (1,085m) – Wales’ highest mountain

The total walking distance is about 23 miles (37km) with a total ascent of 3,064m (10,052ft). The total driving distance, meanwhile, is 462 miles

About 30,000 people attempt this peak-bagging challenge annually, with approximately 90 per cent successfully climbing the three mountains, but with only 40 per cent doing so within 24 hours. 

Do you have to complete it within 24 hours?

Tradition dictates that you should aim to complete the National Three Peaks Challenge within 24 hours, including all driving time. This is usually split across about 14 hours of walking and 10 hours of driving. The common approach is to start your stopwatch at the base of your first mountain before ascending it, and to only stop the timer once you have descended the final peak.

But there are no strict rules and you are free to take on the challenge however you see fit. If you want to take a whole weekend or even a week to complete the challenge, that is completely up to you. Some people choose to walk each of the three peaks on separate occasions, adding up their individual times, for example. Or, if you’re feeling particularly creative and intrepid, you could follow in my footsteps and take on a self-propelled challenge, such as cycling or hiking between the peaks, like Sean Conway did.   

Guided vs Self-organised: should I join a guided group or organise my own challenge? 

Most challengers complete the National Three Peaks Challenge as either part of a guided group or a self-organised group. Joining a guided group can be relatively expensive, but it is the most hassle-free option. Mountain guides will ensure you are safe and don’t get lost during the hikes, and minibus drivers will arrange all of the transport logistics.

Alternatively, you can organise your own challenge with a group of friends. This option is fun, sociable and a wonderful experience, but the burden of admin and logistics will fall on you.

Can I take on the National Three Peaks Challenge solo?

This is not a common approach, but it can be done. Indeed my record-breaking hike was solo and self-supported. Such an approach can sometimes feel lonely, but there are loads of positives too. It is true escapism and freedom to be alone in the mountains - it gives you a greater sense of peace and solitude, and the challenge of being self-reliant can be life-affirming.

Who should do the driving? And how do I organise the transport logistics?

If you are part of a guided group, you have nothing to worry about. Minibus drivers will transport you between the mountains and you are free to relax (or sleep) during the long drives.

If you are organising your own challenge, it is best practice to recruit a minimum of two nominated drivers (who are not taking part in the walk). This ensures the drivers are sufficiently rested to be safe on the road. Not all groups are able to do this, but it is worth thinking carefully about driving safety while planning your adventure.

In terms of vehicles, many challengers use their own cars or hire a minibus, while those on guided excursions travel to the start and finish by public transport (Ben Nevis is close to Fort William train station and Snowdon has links to Bangor and Llandudno Junction stations). 

What order should I do the mountains in? 

Depending on where you live, you may choose to start with Snowdon and travel north, or alternatively start with Ben Nevis and travel south. Scafell Pike is nearly always climbed as the second peak.

Ben Nevis is the most popular start point, with hikers moving on to Scafell Pike and finishing the 'trilogy' with Snowdon. 

What mountain routes should I walk?

Again, this is completely up to you, but the common approach is to follow these three routes:

  • Ben Nevis – climb the 'Pony Track' route starting at Glen Nevis YHA or Glen Nevis Visitor Centre. it is 17km, 1352m ascent, six hours. 
  • Scafell Pike – climb the 'Hollow Stones' route starting in Wasdale Head. It is 10km, 989m ascent, four hours.
  • Snowdon – climb the 'Pyg Track' from Pen-y-Pass car park. It is 11km, 723m, four hours.

You should also think strategically about what time of year and day to commence your challenge. Summer is your best bet for longer daylight hours and a better chance of good weather. In terms of time of day, the optimum choice is to start during the late afternoon (e.g. 5pm) on Day One on Ben Nevis, drive through the night, climb Scafell Pike at dawn (e.g. 4am) on the following day, and then make it up and down Snowdon by 5pm – thus completing in less than 24 hours. This approach minimises the amount of hiking in the dark. Other start times might mean you’re hiking in the dead of night. 

How fit do I need to be? And what training should I do?

This is no easy challenge. Good levels of fitness are required to cope with the distance and ascent involved, and mental toughness is needed to overcome poor weather and fatigue. But, having said that, the National Three Peaks Challenge is well within the grasp of anyone who is determined and dedicated, even if you don’t have much mountain experience.

In terms of training, it might sound ridiculously obvious, but the best way to train is to simply spend as much time in the hills as possible. You will build strength in the relevant muscles, and increase your stamina and endurance. Try and up the mileage, ascent and technicality of terrain each month. 

If you live far from the hills, find an alternative - perhaps fast-walk a set of repetitions up a steep road or even some stairs. Wear your hiking shoes and a fully-laden backpack to add intensity. Or, if the hill reps sound too boring, plan a long hike around your local area, even if it’s pretty flat. If all that fails, simply go for jogs or runs or hit the gym to maintain a good base fitness.

What environmental considerations should I consider?

The normal approach - driving between the three summits in a mad 24-hour rush - has a bit of a bad reputation. You’re tearing up the roads, burning loads of petrol, and ghosting in and out of each region without much consideration for your social and environmental impact (late-night noise in Wasdale Head, at the base of Scafell Pike, is a particular problem).

To minimise your impact, please leave no trace, pick up all litter, keep noise to a minimum, stick to paths (to reduce erosion and trampling of plants), and consider donating to the upkeep of the mountains via the Three Peaks Partnership

Five top tips from the author: a Three Peaks record-holder

  1. Break in your boots: whatever you do, don’t wear your new boots for the first time on the National Three Peaks Challenge - doing so will guarantee excruciating blisters!
  2. Download your route to your phone: using a navigation app such as Komoot or OS Maps enables you to download routes to your phone, meaning you can pinpoint your exact location using GPS (even if you don’t have phone signal).
  3. Consider trail shoes not boots: traditional wisdom says sturdy, heavy, leather boots are needed on big mountains, but such boots can be stiff, rigid and blister-inducing. A more modern approach is to wear trail shoes that are more flexible and forgiving, but still with enough traction to keep you safe over gnarly terrain. 
  4. Carry a power bank: you don’t want your phone to run out of juice (for those summit selfies as well as for safety), so carrying a 20,000mAh power bank will enable you to charge it up whenever you need to.
  5. Expect the unexpected: the weather in the mountains can change in an instant (one minute it’s sunny, the next it’s an apocalyptic storm), so be prepared - carry safety gear, a first aid kit, warm layers, waterproofs and plenty of food and water.
