Moving from road to trail running means shorter, quicker steps, running by effort instead of pace, stronger ankles and the right kit. Trails are softer on your joints and much better for your head, but they ask different things of your body. Here's what changes, and how to make the switch without picking up an injury.
Most of our running now happens on the trails around the Chilterns and Hertfordshire. It took me a while to stop running them like a road.
1. Forget your pace
On the road, you can hold a steady pace for miles. On the trail, pace goes out of the window. Mud, roots, hills and stiles all slow you down, and that's fine.
Run by effort instead. If you can hold a conversation, you're about right for an easy run. A heart-rate watch helps, but your breathing will tell you most of what you need to know. Your first trail runs will feel slow. Everyone's are.
2. Shorten your stride
Long, reaching strides are a road habit that trails punish. On uneven ground, shorter and quicker steps keep your feet under your body, so you can adjust quickly if a foot lands on a root or a loose stone.
- Quick, light steps, especially on technical ground
- Look 2–3 metres ahead, not at your feet
- Use your arms for balance on rough ground and descents
3. Hills: walk more, not less
Walking up a steep hill isn't cheating. On trails, it's often the faster and smarter option. Fast walking with short, quick steps and your hands on your thighs saves energy for the flatter sections.
On the way down, lean slightly forward from your ankles rather than back, keep your steps short and quick, and let gravity do the work. Leaning back feels safer, but it's the fastest way to slip.
4. Build ankle and leg strength
Trails constantly change the angle your foot lands at. Your ankles, calves, hips and core do much more work than on the road, which is great for your running, but only if you build up gradually.
Three simple exercises
- Single-leg balance: 30 seconds on each leg, then try it with your eyes closed
- Calf raises: 3 sets of 15, then progress to single-leg
- Single-leg squats or step-downs: 3 sets of 10 each side, slowly
Twice a week, ten minutes. Do them while the kettle boils.
5. Ease in
Don't swap all your road runs for trail runs at once. Start by replacing one easy run a week with a trail run, and keep it short. Then add more trail time over a few weeks as your legs adapt. Expect sore calves and ankles at first: that's your body learning a new skill.
6. Get the kit right
| Shoes | Road shoes are fine on dry, firm paths. For mud and wet grass, trail shoes with deeper lugs give much better grip. |
|---|---|
| Socks | A snug, moisture-managing sock that doesn't slip on descents. A crew-height cuff helps keep grit and seeds out. |
| Water | On runs over an hour, carry water. There are no shops halfway up a hill. |
| Layers | A light waterproof in a pocket or pack. British weather changes quickly on high ground. |
| Phone | Fully charged, with the route downloaded. Tell someone where you're going. |
Why your socks matter more off-road
On a trail, your foot moves around in your shoe much more than on the road. Every descent pushes your toes forward, every camber tilts your foot, and wet grass and puddles soak everything. That's a lot more friction and moisture, which are the two main causes of blisters.
That's why The Runner's Sock has arch-support compression to hold it in place, targeted cushioning where your foot lands, and nylon to move sweat away from your skin. For more on this, read why your socks cause blisters.
Be a good trail runner
- Follow the Countryside Code: close gates and leave no litter
- Slow down and say hello to walkers, riders and cyclists
- Keep dogs under control around livestock
- Stay on the path, even when it's muddy, to protect the ground around it
Frequently asked questions
How is trail running different from road running?
Trail running is on uneven, changing ground with more hills, mud and obstacles. You'll take shorter, quicker steps, run more by effort than pace, and use your ankles, hips and core much more than on the road.
Should I run slower on trails?
Yes. Expect your pace to be slower than on the road for the same effort. Run by feel or heart rate rather than pace, and walk the steepest climbs.
Do I need trail running shoes?
For dry, firm paths, road shoes are often fine. For mud, wet grass or rocky ground, trail shoes with deeper lugs give you much better grip.
How do I avoid rolling my ankle on trails?
Look a few metres ahead, take shorter steps, and build ankle strength and balance with exercises like single-leg balances and calf raises.
What socks are best for trail running?
A snug, moisture-managing sock with a crew-height cuff helps keep grit out and stops the sock slipping on descents, which reduces the risk of blisters.
If you have a history of ankle or knee injuries, speak to a physio before increasing your trail running.
