How to start

Choose a gentle, well-marked trail and run it at an easy pace, walking the steep uphills. Allow more time than the road: trails are slower.

How to progress

Lengthen your runs gradually, then add hillier routes. Learn to read the ground and take shorter steps on rough terrain.

What the evidence says

Evidence: limited

We found no strong trials on trail running benefits or on injury rates. Running in general is linked with lower death rates (see Jogging), and softer, uneven ground changes how your body loads. We did not find reliable data on whether trails are gentler or riskier than roads, though falls and ankle sprains are a clear extra risk.

Take care: Uneven ground raises the risk of trips, falls and ankle sprains. Tell someone your route, carry water and a phone, and be careful on wet or steep ground.

12-week starter plan

You should be able to run 30 minutes on the road. Do two trail runs a week: one steady and one with some hills. Walk steep sections.

0 of 12 weeks done

Tick each week as you finish it; your ticks are saved on this device only. Repeat a week if it felt hard. Weeks 4, 8 and 12 hold steady so you can settle. This is a general plan, not medical advice.

Add reminders to your calendar

Pick your days and time. You will download a calendar file that adds 12 weeks of reminders to Google, Apple or Outlook calendar.

Frequently asked questions

Is trail running easier on the body than road running?

Softer ground can feel kinder, but uneven terrain adds twists and falls. We found no reliable data on which is safer.

Do I need trail shoes?

For muddy or rocky routes, yes: the grip matters. For smooth, dry paths, road shoes are fine.

How do I stay safe on my own?

Tell someone your route and return time, carry a phone, and stick to known trails until you have experience.

How much slower will I be?

Often a minute or more per mile compared with the road. Use effort, not pace, as your guide.
