Trail Running FAQs: Your Complete Beginner & Training Guide

At Bedfordshire Trail Runners, we’re often asked the same questions by runners looking to get off the pavement and onto the trails. Whether you’re new to trail running or looking to improve your training, here are clear, practical answers to the most common questions.

What exactly is trail running?

Trail running is running on natural surfaces such as woodland paths, hills, fields, or countryside trails instead of paved roads.

What qualifies as trail running?

Any run primarily on unpaved terrain including forest tracks, coastal paths, and countryside footpaths all count as trail running.

What is the 80/20 rule for trail running?

The 80/20 rule means doing around 80% of your training at an easy, conversational effort and 20% at a harder intensity. This approach helps build endurance, improve performance, and reduce injury risk, especially important when running on varied terrain.

What is 80/20 trail running?

It’s simply applying the 80/20 training balance to off-road running, combining relaxed trail miles with occasional hill sessions, intervals, or tempo efforts.

Does 80/20 running really work?

Yes  it’s widely used in endurance training because it helps runners stay consistent, avoid burnout, and steadily build fitness over time.

What is a good pace for a trail run?

Trail running pace depends on terrain, elevation, and conditions, so focus on effort rather than speed. A good easy pace is one where you can comfortably hold a conversation.

Are trail runs harder than road runs?

Trail running can feel tougher due to hills and uneven surfaces, but many runners find it mentally easier and more enjoyable thanks to the scenery and variety.

How much harder is trail running?

Most runners are typically 30–90 seconds per mile slower on trails compared to road running, depending on terrain difficulty.

Is trail running easier on your body than road running?

Often yes.  Softer surfaces reduce impact stress, though trails require more balance and stabilising muscle strength.

What is the difference between trail running and road running?

Trail running focuses more on effort than pace, builds strength and agility, and offers a more varied outdoor experience compared to road running.

What is the hardest type of running?

Ultra trail running and mountain running are generally considered the most demanding due to long distances, elevation gain, and technical terrain.

What are the cons of trail running?

Challenges can include mud, hills, slower pace, uneven footing, and navigation. But many runners find the benefits far outweigh these.

Is it better to walk for 1 hour or run for 30 minutes?

Both offer health benefits. Running is more time-efficient for cardiovascular fitness, while walking is lower impact. The best choice is whichever you can do consistently.

What is the 10% rule in running?

The 10% rule suggests increasing weekly mileage or training load by no more than 10% to reduce injury risk and allow your body to adapt gradually.

How do you apply the 10% rule?

If you run 20 miles this week, aim for no more than about 22 miles next week rather than making large jumps in volume. Examples of the 10% rule:

Increase a 5K long run to 5.5K, move from 10 miles per week to 11 miles, or add a short easy run instead of a long hard session.

Is it true only 1% of people run a marathon?

The exact percentage varies, but marathon running is still a relatively rare achievement making it a meaningful personal milestone.

What is the 80% rule in running?

This usually refers to keeping most training at an easy aerobic effort to build endurance and support recovery between harder sessions.

Can beginners run 10K?
Absolutely with a gradual training plan, consistency, and sensible pacing, most beginners can safely build up to a 10K distance.

Trail running improves cardiovascular fitness, builds strength, reduces stress, and helps you connect with nature making it one of the most rewarding ways to stay active outdoors.
