The Ultimate Guide to Trail Running in the UK

Trail running is one of the best ways to explore the UK’s wild spaces while enjoying a real sense of adventure. You can discover the country’s most beautiful and unspoilt landscapes while getting active and pushing your limits.

However, trail runs often call for a bit more planning and preparation than road running. You need to think about navigation, staying hydrated and what essentials to pack, all the while exploring quite remote areas.

At Adventure Tours UK, trail running is a big part of what we do. When it comes to expert advice, we always turn to our in-house guide and coach, Tim Higginbottom. As a UKA-qualified fell and trail coach (and all-round legend on the trails), Tim knows everything there is to know about off-road running. In this guide, he shares everything you need to know about UK trail running.

What is Trail Running?

Let’s get back to basics: what is a trail run? Trail running is generally defined as off-road running, usually on ‘easier’, well-maintained paths and tracks.

Trail runs often wind along open fields, follow hillsides and across mountain ranges. They are often well-marked and don’t involve anything too technical or risky, like scrambling over rocks or worrying about steep drops.

Trail running offers a great way to enjoy the outdoors and explore lesser-trodden landscapes, far away from the pavement or traffic.

Trail Running in the UK
Trails offer a fantastic way to uncover the variety of landscapes that lie waiting to be explored all over the UK. From rolling hills and rugged coastlines to forest trails and peaceful moorlands, there are so many different kinds of routes to explore.

One of the best things about trail running in the UK is how accessible it is. Whether you live near a national park or in a city centre, chances are there’s a trail not too far away.

In recent years, trail running has really taken off in the UK, especially with the rise of ultra-distance events and challenges which often follow trail routes. This has led to many runners discovering how fun it is to push themselves surrounded by epic natural scenery.

The Best Trail Running Gear for Trail Running in the UK

When you first start as a beginner trail runner, you won’t need any more kit for trail running in the UK than you would for a park run or general road running. A good pair of running shoes, some comfortable kit and a sense of adventure will take you a long way.

However, as you catch the bug, you will begin exploring more remote or challenging routes. Some trail running kit can make your experience much safer, more comfortable, and a lot more enjoyable!

Trail Running Shoes
One of the first upgrades you’ll want to make is to trail-specific shoes. There’s almost an infinite variety of outsole types to choose from to suit each type of trail and season.

Start with a versatile pair rather than going straight for heavily studded mountain shoes. These can be uncomfortable on harder paths and wear down quickly if you’re not on rugged ground all the time.

Running Sacks
As you become more curious and want to follow longer trails, you’ll need to be able to carry food, water, maps and spare kit with you, which is when a running sack comes in handy. There is a huge range of ‘limpet’ style running sacks available now to choose from, and 10 litres offers ample room for most people.

Trail Running Clothing

When it comes to what to wear trail running in the UK, there are a few must-have pieces that will keep you much more comfortable on the trails:

A Waterproof Jacket
Invest in a high-quality, lightweight waterproof jacket with a hood. Given the unpredictable weather in the UK, it’s essential to keep you comfortable in rain showers and on windy days.

Buff
A buff can protect your head or neck from the sun, wind, or cold while trail running in the UK.

Gloves & Sun Cap
Gloves and a sun cap are also key items for trail runs in the UK. Lightweight gloves are great for cooler days, while a breathable running cap helps protect you from the sun.

Sunglasses
Sunglasses are also a great idea. Wraparound or sports-style shades are particularly effective at blocking the sun and trail debris.

Suncream
Yes, even in the UK, sun cream is an essential. You’d be surprised by how strong the rays can be even on cloudy days. After all, you’re likely out running for several hours with minimal shade. Carrying a small refillable container of sun cream is a great idea when it’s particularly sunny.

Hydration Options
Staying well-hydrated is key on the trails, and there’s quite a few nifty hydration options and vessels to choose from. It depends on how far you are running and how you’d prefer to carry your water.

Two 500ml flexible or collapsible soft bottles are often the best choice. They provide better balance than a single large bottle, fit neatly into the front pockets of a running vest. They are also quick and easy to refill at water stops.

Larger hydration bladders, like CamelBak-style systems, can work for some runners. However, they tend to get warm against your back and are trickier to refill mid-run. For most UK trail runs, soft flasks tend to be the most practical and comfortable option.

The Best Places to Go Trail Running in the UK

Every region of the UK has stunning trails to follow. Some are well publicised on tourism sites, while others are waiting to be discovered and are ‘well-kept secrets’!

While the best places to go trail running near you aren’t always immediately obvious, often using public transport for only a short distance can unlock a scenic point-to-point (linear) route instead of looping back or settling for a less inspiring circular path. Top tip: get a ride out and run back so you’re not rushing to catch the last bus!

Here are some of the top places to go to experience the best trail runs in the UK:

UK National Parks and Mountain Areas
The UK’s national parks, like Eryri (Snowdonia), the Lake District, the Brecon Beacons, and the Scottish Highlands, are perfect for trail running. While many think of these places as steep and rugged, there are often gentler valley trails and flatter valley routes that offer stunning scenery and easier navigation.

The UK’s national park and mountain trail running routes are usually well-marked and well-documented on park websites. This makes them very accessible for trail runners, new and old to the sport!

An awesome way to be an ‘adventure tourist’ is to go on weekend-long trail running holidays to explore these landscapes. These give you the chance to tick off two trails, a taste of the area, and an excuse to refuel!

Adventure Tours UK runs Spring and Autumn trail running camps close to Eryri (Snowdonia) National Park. These offer brilliant opportunities to discover what it is like to trail run across this legendary park. You’ll have the assurance of travelling as a group and under the guidance of an expert coach.

Urban Trails, Canal Networks and Former Railway Lines
You don’t have to head to the mountains to enjoy the best trail running routes. Even in cities, there are often surprisingly adventurous routes to discover. The UK’s extensive canal network and converted railway paths often give direct access between city centres and the countryside or scenic trails.

Less obvious but equally rewarding, these running routes are often flatter and easier to follow, while still offering beautiful scenery and a peaceful atmosphere. They are great places to go trail running in the UK – no need to head for the hills!

UK Coastline

Much of the UK’s coastline now has well-established paths running along it, which are perfect for scenic trail runs. Just be prepared: while the views are incredible, some sections can be seriously hilly! These coastal trails are perfect for anyone planning a trail running holiday in the UK and looking for a challenge.

Remote Areas
More remote parts of the UK, like the Scottish Highlands or North East England, provide a real sense of adventure for trail runners. While there are some well-marked trails, these regions can be quite isolated, so you need to know your limits before going for these challenging routes!

Long Distance Walkers Association Events
The Long Distance Walkers Association (LDWA) organises hundreds of events all year round across the country – not just for walkers, but trail runners too. These offer some support for those who want it by way of refreshments en route, a set course and plenty of others taking part around you.

As opposed to being races, these are relaxed and supportive events, with no pressure to finish fast. Some participants run the entire route, while others prefer to walk. It’s worth bearing in mind that the LDWA trail running events have become so popular that most now require pre-registration.

Long-Distance National Trails
You don’t have to tackle long-distance routes all at once – split them over weekends to explore different parts of the UK. Offa’s Dyke lets you experience Wales end to end, while the West Highland Way offers a great intro to Scotland’s wild side.

The Pennine Way is now home to the iconic Spine Race, but is also a brilliant place to explore on its own terms. These UK trail running routes are well marked, supported by guidebooks and maps, and make excellent choices for trail running holidays UK.

Navigating UK Trail Running Routes

For many, the idea of navigating unfamiliar trail running routes can be a bit daunting, but there are lots of ways to make it easier. I’ve shared some of my top tips below:

Join a Trail Running Community
Joining a trail running UK club (or regular running club with trail sections) is a great way to build confidence. This allows you to learn from others and connect with like-minded runners who know the local routes.

Use Tech to Guide You
There are now plenty of apps offering route suggestions and downloadable GPX files. You can follow these on your phone or GPS watch, making it much easier to navigate your trail runs. Many newer watches come with built-in maps and turn-by-turn directions, making it easier than ever to stay on track.

Run with a Friend
Finding a running buddy can make a huge difference – not just for motivation, but also for sharing navigation duties. If you want to improve your skills, consider joining your local orienteering club. They host regular beginner-friendly events and are fantastic at teaching the basics.

Subscribe to Ordnance Survey
The UK is lucky to have some of the best mapping available in the world. A small subscription to the Ordnance Survey app gives you access to thousands of trail running UK routes across the country – perfect for discovering new trails and planning your next adventure with confidence.

The Best Time of Year to Go Trail Running in the UK

One of the best things about trail running in the UK is that it promises a very different experience each and every season. The same trail can feel completely different depending on the time of year you’re visiting. Here’s a breakdown of the best times of year for UK trail running:

Winter
Winter trail runs promise the most dramatic landscapes. On top of the impressive natural scenery, you can enjoy clean, crisp air when running at this time of year. Wrap up and enjoy the quiet beauty of the trails. Just keep in mind that you might need to slow your pace and be extra cautious, as muddy, wet or icy conditions can make the trails trickier.

Spring
Spring is hard to beat. Nothing beats trail running to the sounds of bleating lambs and the general feeling of new growth in the air. Plus, the scenery is stunning as the landscapes come alive with fresh greenery and blooming wildflowers. The lighter days and milder temperatures make it an ideal time for both beginners and seasoned runners to explore the UK’s best trail running spots.

Summer
Trail running in the UK in summer means enjoying the freedom of running in just a t-shirt and shorts, with the sun on your back and dry trails underfoot. The long daylight hours make it the perfect season for evening adventures during the week and post-run café or pub stops.

Autumn
Expect colourful landscapes and earthy scents in the air when exploring the UK’s trail running routes in Autumn. It’s worth noting, however, that you’re always gambling with the weather at this time of year. Some days are warm enough to be heading out in just a t-shirt, while others call for your full winter trail running kit. Either way, it’s the season for finishing trail runs at a cosy pub where you can warm up by the fire.
