Updated September 2026

My first proper trail run was on the Mendips on a warm May day, just after completing a marathon. I needed a ‘different’ run after miles of pounding the pavements, and a friend suggested we head off road instead. I remember thinking how extraordinary it was. The same legs that had ground through 26 miles of tarmac felt completely different on soft ground with a view. I was hooked immediately.

That was several years and many trail races ago. I am now a UKA-qualified running coach, and I introduce runners to trail regularly. The same thing happens almost every time. They come back with a look on their face that says Why did I not do this sooner.

This guide covers everything you need to know to get started: kit, mindset, safety and the mistakes I see beginners make most often.

Why Trail Running Feels So Different

Trail running is not road running on a different surface. It is a fundamentally different experience. The terrain changes constantly beneath your feet, soft grass, mud, rocky paths, woodland roots, open hillside. Your body has to adapt and respond rather than repeat the same movement over and over. Your mind has to stay present in a way that road running simply does not require.

Most runners who try it find that this presence is exactly what they needed. You cannot zone out on technical trail. You cannot worry about work when you are picking your line through a rocky descent. That enforced focus is one of the most underrated benefits of trail running and one of the main reasons runners who start on trail rarely want to go back to road only.

The other thing you notice immediately is how much kinder it feels on your body. Softer ground absorbs impact rather than returning it. Varied terrain distributes load across a wider range of muscles rather than hammering the same structures with every stride. Many runners whose knees or shins struggle with road running find trail significantly more comfortable.

The Biggest Mistake Beginners Make

Being a slave to the watch.

I see this constantly with runners making the switch from road to trail. They set off at their road pace, their watch shows them something slower, and they push harder to compensate. By mile four they are struggling, and by mile eight they are walking, not because they chose to but because they burned through their energy chasing a pace that was never appropriate for the terrain.

Trail pace is not road pace, and it should not be. A runner who comfortably runs six-minute kilometres on road will be closer to eight or nine minutes per kilometre on mixed trail with any elevation. That is not failure; that is physics. Use our trail running pace calculator to get a realistic estimate for your route before you head out.

The other watch-related mistake is checking distance obsessively. Ten miles on trail is not ten miles on road. It takes longer, it demands more from your body, and it should be measured in time and effort rather than kilometres. Go out for ninety minutes rather than ten miles. You will have a better run.

The mindset shift is simple: trail running is about enjoying the run rather than pounding the pavements for speed. Once you make that shift, everything else clicks into place.

Where to Start

Choose a route you can manage

For your first trail run, start shorter than you think you need to. If you are a comfortable road runner who regularly covers ten miles, aim for five to six on trail. The terrain, the elevation and the concentration required will make those miles feel significantly harder than road miles at the same effort level.

Start on marked paths rather than open fell or mountain terrain. Footpaths, bridleways and waymarked trails give you the trail experience without the navigation demands. Your local woodland, country park or coastal path is a completely legitimate starting point.

Have a plan before you leave

Unlike road running where you can always flag down help or duck into a shop, trail running takes you away from infrastructure. Have a clear plan of where you are going before you set off. Download the route to your watch or phone so you can navigate if you lose the path. Tell someone where you are going and how long you expect to be. Take a fully charged phone.

This is not about being dramatic; it is about being sensible. Trails are quieter than roads, and if something goes wrong, you want someone to know where to look. See our trail running safety for women guide for more on staying safe on the trails.

Go with someone if you can

Your first trail run is a better experience with someone who knows the local trails. They will show you routes you wouldn’t find on your own, warn you about tricky sections, and share the experience of discovering something new together. If you are a club runner, ask whether anyone else in your club runs trails; you may be surprised how many do.

Trail Running Kit for Beginners

You do not need to spend a fortune to start trail running, but there are a few pieces of kit worth getting right from the beginning.

Trail shoes — the most important purchase

Road shoes are not appropriate for trail running. They lack the grip, the lateral stability and the outsole protection that off-road terrain demands. The first wet rock or muddy descent will make this very clear.

For most beginners on mixed terrain, the Hoka Speedgoat 7 is the most natural starting point. The Vibram Megagrip outsole handles wet rock, wet grass, hard-packed trail and mixed terrain with equal confidence. The wide base provides stability on uneven ground and the generous cushioning protects your feet on technical sections. It is the shoe I see most consistently at UK trail race start lines and the one I most commonly recommend to runners making the switch from road.

Once the mud arrives properly, and in the UK it always does, the Salomon Speedcross 6 is the specialist choice. The 8mm chevron lugs bite through soft ground and release mud cleanly. If you run through autumn and winter in the UK, you will eventually want a pair.

A GPS watch

You do not need an expensive GPS watch to start trail running, but one that shows grade-adjusted pace changes how you manage effort on hilly terrain. It removes the confusion of watching your pace spike on every uphill and gives you a more honest picture of your actual effort. The Garmin Instinct 3 at around £349 is the most sensible starting point for a trail runner who wants serious GPS capability without the complexity or cost of the premium range. See our best Garmin watches for trail running guide for full recommendations.

A running vest or belt

For shorter trail runs of under an hour, a belt that carries a water bottle and your phone is sufficient. For anything longer or more remote, a small running vest gives you the carrying capacity for water, nutrition, a waterproof jacket and a phone without bouncing or chafing. See our best trail running vests guide for recommendations across distances and budgets. If you are unsure whether you need a vest or a belt, see our running vest vs hydration belt guide.

A headtorch for darker months

If you run in autumn or winter and want to get out before or after work, a headtorch is essential on trails.

Merino wool socks

A small investment that makes a disproportionate difference to blister prevention on longer efforts. Worth adding to your first trail kit order alongside your shoes.

Technique Tips for Beginners

Walk the uphills without guilt. The best trail and ultra runners in the world walk steep climbs. It is not weakness; it is strategy. Power hiking a sustained climb at a controlled effort is often faster and always more economical than trying to run it. Give yourself permission to walk uphills from your very first trail run.

Look ahead, not at your feet. On technical ground, the instinct is to watch your feet. Resist it. Looking three to five steps ahead gives you time to pick your line and react to obstacles. Looking at your feet means you never see what is coming.

Shorten your stride on descents. Running downhill on trail is a skill that takes time to develop. Short fast strides give you more control and more contact with the ground than long bounding ones. Relax your upper body. Start on familiar gentle slopes at a pace slightly faster than comfortable and build gradually.

Slow down on leaves and wet rock. Autumn leaves on trail hide the technical ground beneath them and are genuinely slippery when wet. Wet rock after a dry summer is particularly treacherous. Slow down on both. No session is worth a rolled ankle.

Trail Running Etiquette

  • Leave only footprints. Take litter home, leave gates as you find them and respect the countryside you are running through.
  • Give way to horses. Give them space and slow to a walk if they seem unsettled.
  • Be courteous on shared paths. A simple hello goes a long way on a quiet trail.
  • If you run through livestock fields, be calm, give animals space, and never run directly at them.

Your First Trail Race

Once you have found your feet on the trails, entering a race gives you a goal to train toward and introduces you to the trail running community properly. Start with a shorter marked course, a trail 10k or a local trail series event, rather than a navigation race or fell race.

For runners ready to step up to fell racing our guide to how to train for your first fell race covers everything from training to mandatory kit to what to expect on race day. For what to wear on race day see our what to wear for a trail race guide.

Frequently Asked Questions

How far should I run on my first trail run?

Shorter than you think. If you are a comfortable road runner who covers ten miles, aim for five to six on trail. Trail running takes longer, demands more concentration and uses muscles road running does not. Build gradually and go by time rather than distance.

Do I need special shoes for trail running?

Yes. Road shoes lack the grip, stability and outsole protection that trail running demands. A trail shoe with a grippy outsole is the single most important kit purchase for a beginner trail runner. The Hoka Speedgoat 7 is the most versatile all round starting point for most runners on most terrain.

Is trail running harder than road running?

Different rather than harder. It is typically slower and more technically demanding but many runners find it less hard on their bodies despite feeling more challenging aerobically. See our road to trail running guide for the full breakdown.

How do I find trail running routes near me?

OS Maps, Komoot and Strava Route Builder are the most useful tools. Joining a local running club or trail running group is the fastest way to discover the best local routes with people who already know them.

What should I carry on a trail run?

A fully charged phone, enough water for the distance, some food for anything over ninety minutes and a waterproof jacket in the UK at any time of year. Tell someone where you are going and how long you expect to be before you leave.

Can I trail run alone as a woman?

Yes, with sensible precautions. Stick to familiar routes, share your location with a trusted person, leave headphones out on isolated trails and trust your instincts. See our trail running safety for women guide for detailed advice.

How much slower is trail running than road running?

Typically one and a half to two minutes per kilometre slower on mixed terrain with moderate elevation. Use our trail running pace calculator for a route-specific estimate.
