Trail Running Guide for Beginners: Tips, Technique and Equipment

Connect directly with nature, put your biomechanical abilities to the test and unleash your wild side. Discover everything you need to know to get started in trail running with confidence.

“In the mountains, you learn that you are very small: a falling rock or a sudden storm can wipe you off the map. That makes me put everything into perspective and understand what really matters.” — Kilian Jornet.

What is trail running?

Trail running is a discipline where you and the mountains are on exactly the same team. Put simply, trail running consists of running off-road, surrounded by nature.

Unlike road running —where asphalt and even terrain predominate—, mountain runners face technical trails, steep elevation changes, muddy sections, loose rocks (scree) and roots.

According to the definition of the ITRA (International Trail Running Association), trail running includes any foot race held in a natural environment (mountains, forests, deserts or plains) on unpaved surfaces, where asphalt must under no circumstances account for more than 20% of the total route.

Trail running has gone from being a niche discipline to becoming a rapidly growing global phenomenon.

Trail running distances vary widely: they range from explosive orienteering events or routes of less than 5 km (such as Vertical Kilometres) to ultra-distance events (UTMB) that comfortably exceed 100 or 160 km, with staggering cumulative elevation gains.

Trail running and connecting with nature

Running outdoors doesn’t just train your legs; it recalibrates your central nervous system.

If you regularly practise conventional running, you’ll know that heading outdoors for a run produces an unparalleled feeling of freedom. This response is not purely subjective: scientific evidence supports the benefits of physical activity performed in green environments (a phenomenon known as Green Exercise), showing positive effects on serum cortisol reduction, heart rate variability (HRV) and overall mood.

Trail running enhances emotional adaptations and strongly stimulates proprioceptive focus thanks to the biomechanical richness of the environment.

Tips for getting started with trail running

Your road-running pace doesn’t apply in the mountains. And that’s perfectly fine: the key here is effort management and proprioception.

It is very common for runners with impressive 10K or Half Marathon road times to experience considerable frustration during their first trail runs. The reason is simple: the energy demands and mechanical patterns are completely different.

The irregularity of the terrain directly affects running technique and stride type. While road running prioritises linear running economy and the elastic rebound of the Achilles tendon, in the mountains the following become particularly important:

Trail running equipment

Unlike road running, the mountains require you to be self-sufficient. Equipment is not just a matter of comfort, but of biomechanical safety and basic survival.

Technical clothing

Prioritise garments made from highly breathable synthetic fabrics (such as high-density polyester or polyamide) that efficiently wick away sweat and help prevent chafing.

Trail-specific running shoes

Making the mistake of heading into the mountains in conventional road-running shoes drastically increases the risk of ankle sprains or falls due to insufficient traction. Investing in mountain-specific footwear should be a priority.

Hydration and nutrition strategy

Sweat rate and muscle glycogen consumption increase considerably during trail running due to the constant eccentric and concentric muscular demands of climbing.

Running with a rigid bottle in your hand alters the biomechanics of your arm swing and is inefficient. The most recommended solutions include:

A good trail running vest allows you to carry hydration, electrolytes, energy gels and mandatory equipment without compromising your mobility.

Lighting and safety equipment

Mountain conditions are changeable, and visibility can quickly deteriorate due to fog or nightfall.

Post-workout change of clothes

As most training sessions involve travelling by car to the start of the trail or track, keep a complete set of dry clothes ready in the boot (T-shirt, clean socks and comfortable footwear).

This will help you avoid peripheral vasoconstriction caused by cooling down and help support your immune system after exercise.

Tips for your first trail running races

Experience is the only way to progress. Adapt your mindset to the environment and enjoy the learning process. If you’re ready to take the leap and tackle your first kilometres in the mountains, follow these tactical recommendations to ensure a smooth, injury-free transition:

Running technique on slopes and continuous decision-making are skills that improve with practice.

Start with less technical routes

There are two main categories of trails: non-technical (wide forest tracks, greenways and compact dirt paths) and technical (ridges, narrow trails with plenty of loose rocks and steep gradients).

• Start on wide, non-technical tracks. This will allow your muscular and joint structures to adapt to elevation changes without placing excessive stress on your neuromuscular system.

Forget about pace per kilometre

In trail running, min/km is not meaningfully comparable with road running. On average, your pace per kilometre may be 20-40% slower depending on positive elevation gain (D+) and terrain difficulty. Use RPE (Rate of Perceived Exertion) or your heart rate zones as a guide rather than the stopwatch.

• The main objective on your first outings is efficient energy management and completing the route safely.

Walking is a strategy, not a defeat

In professional trail running, walking on steep climbs is part of the energy-management strategy. Power hiking while placing your hands on your quadriceps (or using trail running poles) optimises glycogen expenditure and preserves your muscles for flat or downhill sections.

• If the gradient exceeds 10-15%, walking at a brisk pace is more energy-efficient than trying to maintain a forced running pace.

Constantly scan the terrain

To avoid trips or twisted ankles, train your visual focus. Don’t stare directly at your feet or look too far ahead towards the summit. Keep your gaze focused between 3 and 5 metres in front of you to anticipate your foot placement.

• Apply the “terrain-reading” technique: your brain will process obstacles before you reach them, allowing you to adjust your cadence and lift your knee sufficiently to clear roots or rocks without compromising your balance.

Prioritise safety over performance

Caution is your best ally in the mountains. Before heading out to train:
