Trail Race Guide: How to Choose Your Next Challenge

A morning in the hills, new paths to explore and a finish line that feels even sweeter after that final climb. If you’re looking for a challenge beyond the road, a trail race could be your next adventure.

But how do you choose? A short distance can hide demanding climbs, while a longer route might follow gentler, more runnable paths. Before a race poster or a beautiful landscape wins you over, take a closer look at what’s involved.

This guide will help you find a trail race that suits your experience, preparation and goals.

Distance is only the starting point

On the road, distance is often the first thing you consider when choosing a race. On the trails, you should also look at elevation gain and terrain.

Elevation gain, often shown as D+, is the total amount of climbing along the course. A race with 600 metres of elevation gain includes that much uphill across the route — it doesn’t necessarily mean one continuous 600-metre climb.

Then there’s the surface. Wide dirt tracks, narrow paths, rocks, roots and mud can make two races of the same distance feel very different. Check the course map and elevation profile to understand where the challenges are.

Before choosing, put three things together: how far you’ll go, how much you’ll climb and what you’ll be running on.

What kind of race are you looking for?

Rather than choosing the longest distance you think you can finish, consider the experience you want.

Trying trail running for the first time?
Look for a course that lets you discover the sport without spending the whole race at your limit. A distance you already feel comfortable with is a useful starting point, but always check the elevation gain and terrain too.

Already running trails and ready for a new goal?
You might choose more climbing, a different type of terrain or a longer distance. Think about which challenge appeals to you and whether you can prepare for it in training.

Planning a race day with friends of different abilities?
Look for events with several distances or a walking option. Everyone can choose their own challenge while sharing the same event experience.

Labels such as “mini-trail” or “short trail” can help you identify options, but they don’t replace reading the course details.

Read the race rules before signing up

The poster gets you interested. The race rules help you prepare.

Check the start times, cut-off times, aid station locations and mandatory kit. ITRA identifies equipment, course markings and aid stations as relevant elements of race safety.

Remember the practical details too:

• Where and when to collect your race number.
• Whether the start and finish are in the same location.
• Whether you need to book transport provided by the organiser.
• What your entry fee includes.
• The conditions for changing or transferring your entry.

If anything is unclear, ask the organiser before registering.

Prepare for the course, not just the distance

If you mostly train on roads, use your preparation to explore terrain similar to the race course. Spending time on climbs, descents and uneven surfaces helps you understand how you move and which equipment works for you.

On trails, your pace changes with the terrain. Walking a steep climb can be part of your strategy, and pace per kilometre becomes less useful than it is on a flat road. Give yourself time to adapt and pay attention to the path ahead.

Think about what you want to take away from the finish line, too. Exploring a new mountain range, completing your first off-road race or feeling more confident on descents are meaningful goals alongside a finishing time.

What should you bring on race day?

Start with the organiser’s mandatory kit list. Use it to guide your packing, including any updates shared before the event.

Try your equipment beforehand: shoes, clothing and whatever you’ll use to carry water. Comfort and suitability for the terrain should guide your choices.

The day before, lay everything out and check the organiser’s final instructions. A relaxed race morning starts with fewer decisions left to make.

Enjoy the trails and leave them as you found them

Part of the experience is the landscape around you. Keep wrappers with you until you reach a bin, stay on the marked course and follow the organiser’s instructions.

Reducing the impact of events on natural spaces is also one of the principles promoted by ITRA’s environmental charter.

Find your next trail race

Your next finish line could be in a mountain range you’ve never visited or on a trail close to home. Choose a race that sparks your curiosity and suits your preparation.
