Navigation for Trail Runners — Map, Compass and GPS
Navigating at running pace is a different skill from navigating on a walk. Everything happens three times faster, and the mistakes compound before you notice them.
You do not need to be an orienteer. You need enough to keep track of where you are while moving, and enough to get yourself off a hill in cloud when the GPS dies.
This is the sequence we teach on guided days, in the order it actually matters.
The four skills, in priority order
- Thumbing the map. Keep your thumb on your current position and move it as you go. If you always know where you are, you never need to relocate.
- Setting the map. Turn the map so it matches the ground. It feels trivial and it prevents most gross errors.
- Taking and following a bearing. The one skill that saves you in cloud on a featureless plateau.
- Pacing and timing. Know roughly how long 500 m takes you at hiking and running pace, so you know when you've gone too far.
Handrails, catching features and attack points
- Handrail — a wall, stream, fence or ridge you follow. The lazy, reliable way to navigate at speed.
- Catching feature — something unmissable beyond your target (a road, a river, a col) that tells you you've overshot.
- Attack point — an obvious feature near your target, from which you take a short precise bearing rather than a long imprecise one.
Used together, these three let you move fast and stay found without constantly stopping to check.
GPS: use it, don't trust it
A watch or phone with an offline map is genuinely useful and there's no purity in refusing it. But batteries die in the cold, screens fail in rain, and a route file tells you where you should be, not where you are if you've drifted. Carry a paper map and compass as well — they weigh almost nothing and never run out.
The plateau problem
Ben Nevis, Scafell Pike, Kinder Scout and the Cairngorm plateau share the same hazard: broad, featureless summit ground with steep drops nearby and frequent cloud. On this terrain, take your bearing before you're in cloud, walk it precisely, and count your paces. This is where people get hurt, and it's the one situation where speed is your enemy.
How to practise
- Navigate a familiar area in poor visibility, where a mistake is harmless
- Cover the GPS on a route you know and check yourself against the map
- Set yourself relocation exercises: stop and work out exactly where you are from the ground
- Book a guided day and ask the guide to hand you the map
Frequently asked questions
Do I really need a map and compass if I have a GPS watch?
Yes. Batteries fail in cold weather and a GPS shows your planned route rather than the safest way off the hill. On UK mountains, a paper map and compass are the backup that actually works.
What map scale is best for trail running?
1:25,000 for detailed navigation on open moor and mountain, 1:50,000 for long-distance route running where you're following an obvious line and want less paper.
How do I navigate in cloud?
Take your bearing before visibility drops, follow it precisely, count your paces to measure distance, and use catching features so you know when you've gone too far.
