How To Plan A Trail Running Route

This guide explains how to approach how to plan a trail running route, including the preparation, practical steps, common mistakes, and final checks that help you finish with confidence.

Before You Start

Before you dive into plotting your perfect trail run, ensure you have the necessary tools and mind-set. Careful preparation makes the planning process smoother and your eventual run much safer.

Check first: Always tell someone your planned route, estimated return time, and who to contact if you don't check in by a certain time. Mobile signal can be unreliable in remote GB areas, so don't solely rely on your phone for communication in an emergency.

Common Problems When Planning A Trail Running Route

Even with careful planning, issues can arise. Knowing common pitfalls helps you avoid them or react effectively.

Misjudging Distance or Elevation

Many new trail runners underestimate how much longer and harder a trail kilometre feels compared to a road kilometre. Hills, uneven ground, mud, and technical sections all slow you down significantly. A 10km trail run with 500m of ascent might take as long, or longer, than a 15-20km road run.

Fix: Start conservatively. Add a buffer to your estimated time. If a route looks challenging, consider a shorter version. Use the "rule of thumb" for pacing: 1 hour for every 5km on flat ground, plus 1 hour for every 600m of ascent, then adjust based on your personal trail pace. Always consult the elevation profile before committing.

Relying Solely on Digital Navigation

Smartphones and GPS watches are fantastic tools, but they have limitations. Batteries die, screens crack, and signals drop out, especially in valleys or dense woodland. Getting lost because your device failed is a common and dangerous problem.

Fix: Always carry a fully charged phone with offline maps, and ideally, a backup power bank. Critically, learn to read a paper map and compass, and carry them for all but the shortest, most familiar routes. Practice these skills in a low-risk environment.

Ignoring Weather Forecasts

The weather in the GB, particularly in upland areas, is notoriously changeable. What starts as a sunny day can quickly turn into rain, fog, or even snow, even in summer. Heading out unprepared for a sudden change can lead to hypothermia or poor visibility.

Fix: Check multiple, specific weather forecasts (especially mountain forecasts) immediately before your run. Pack layers, waterproofs, and adjust your route if severe weather is predicted. "There's no such thing as bad weather, only bad gear" holds true.

Choosing Overly Technical Terrain

Some trails are more suited to fell running or scrambling than general trail running. If a route involves steep, rocky ascents, scree slopes, or significant bogs, it might require different footwear, specific skills, and a higher level of confidence than you possess.

Fix: Examine map symbols carefully. Look for terms like "scree," "rough pasture," or "rocky track." Read route descriptions from other users online if available. If in doubt, choose a less technical path or walk the route first without running gear to assess it.

Lack of Escape Routes

Getting deep into a remote area without a clear way to cut the run short if you're injured or fatigued can turn a problem into a crisis. Not knowing how to get back to a road or populated area is a serious oversight.

Fix: As part of your planning, actively identify "bailout points" – junctions with roads, other accessible paths, or small villages. Know their locations and potential transport options. This allows you to make informed decisions if you need to end your run early.

How To Plan A Trail Running Route FAQ

How do I estimate how long a trail run will take?

A good starting point is to use your average road running pace and then slow it down significantly for trails. A common rule for walking is 1 hour for every 5km on flat ground, plus 1 hour for every 600m of ascent. For running, adjust this by your actual trail pace, but always add extra time for climbs, technical sections, and stops. It's almost always better to overestimate than underestimate.

What's the difference between a footpath and a bridleway in the GB?

In the GB, a public footpath is for walkers only. A public bridleway can be used by walkers, horse riders, and cyclists. A byway open to all traffic (BOAT) can be used by walkers, cyclists, horse riders, and vehicles. It's important to respect these distinctions, as they dictate legal access and impact trail conditions.

Should I always carry a paper map and compass?

For any significant trail run, especially in remote or unfamiliar areas, carrying a paper map and compass is highly recommended. Electronics can fail due to battery, signal, or damage. A paper map is a reliable backup that doesn't rely on power. Learning how to use them is essential.

How do I find out about trail conditions (e.g., mud, closures)?

Check local council websites, national park visitor information, or specific trail running groups on social media. Many areas have local groups that share up-to-date conditions. Recent weather (heavy rain, snow) is also a strong indicator of potential mud or difficult ground.

What if I encounter livestock on my planned route?

If you encounter livestock, especially cattle with calves or sheep with lambs, give them a wide berth. If you have a dog, keep it on a lead and under close control. Never get between a parent and its young. Close gates behind you to prevent livestock from escaping. The Countryside Code provides clear guidance on these interactions.
