Key takeaways:
- Unlike what many people think, trail running is a sport for everyone.
- Most beginners start with a 10 to 15 km trail at an average pace of 7 to 11 km/h.
- A good rule of thumb: you're ready for an official trail race when you can cover 75% of the race distance in training.
- Consistency and variety in your training (easy runs, long runs, intervals, specific sessions…) are essential to keep progressing.
Trail running isn't just running — it's an adventure in the heart of nature that engages your whole body. The discipline may look intimidating, but it's genuinely accessible to everyone, as long as you respect a few principles of gradual progression and accept that road running rules simply don't apply here.
Speed, pace and distance: key benchmarks for the beginner trail runner
To get a clear picture of your level during your first outings, here are the key figures and indicators to know:
- Average beginner speed: On a rolling, non-technical trail, it typically sits between 7 and 11 km/h.
- The elevation equivalent: In trail running, 100 m of positive elevation gain (D+) is equivalent to 1 km of extra effort on flat ground. A 10 km route with 500 m D+ therefore equates to roughly 15 km of effort.
- Pace management: Unlike road running, walking on the uphills is a smart effort-management strategy. Your pace can drop to 4 or 5 km/h on steep climbs without it being a sign of poor fitness.
- The ideal distance to start: Most beginners aim for formats of 10 to 15 km for their first official race experience.
Who can do trail running?
Often seen as a discipline reserved for extreme athletes, trail running is in reality open to everyone, regardless of age. Whether you're 20 or a motivated senior, what matters is your desire to explore wide open spaces!
If you come from road running, you already have a cardio base. If you come from hiking, you already have "mountain legs". Trail running is where these two worlds meet. No need to be an expert — short outings on non-technical trails are a perfectly solid way to start.
The secret to progression: avoid injury at all costs
The most common beginner mistake is doing too much, too soon. In trail running, muscles and tendons are put under asymmetric and intense stress, especially on the descents.
- The rule of gradual progression: To progress well in trail running, don't increase your weekly volume by more than 10% from one week to the next. Your cardiovascular fitness improves faster than your joints — give your tendons time to strengthen.
- Listen to the signals: A persistent pain isn't "just part of the process" — it's your body's alarm bell. Trail running should remain a lasting pleasure.
Overall training: strength work and cross-training
To become a well-rounded, resilient trail runner, putting all your eggs in the running basket isn't the smartest approach.
- Strength training: Essential to protect your knees and ankles. Two 30-minute sessions per week, pushing close to muscular failure, can already make a massive difference to your ability to handle elevation gain.
- Cross-training: Cycling, swimming or cross-country skiing are a trail runner's best allies. They build your aerobic endurance without the punishing impact of running. The ultimate trick for boosting your cardiovascular capacity while giving your joints a rest.
Structuring your sessions: building a solid training plan
A solid trail training plan is built on session variety. To avoid running blind, start by determining your MAS (Maximal Aerobic Speed).
A simple method to calculate it: perform a 12-minute test on flat ground — divide the distance covered (in kilometres) by 2, then multiply by 10. For example, if you cover 3 km in 12 minutes, the calculation is: (3 / 2) x 10 = 15 km/h. This baseline figure will then allow you to set your target paces for easy runs, intervals and long runs.
A sample training week:
- Easy Run (Recovery): A slow session of under one hour.
- Long Run: Endurance work on varied terrain. This is also where you validate your gear in real conditions.
- Intervals: To improve your running pace.
- Specific Session: Hill work for power and technique to improve your downhill running in trail.
Gearing up right: technical kit in the service of comfort
- Shoes: Your first line of defence. They must deliver grip and stability. If you're unsure, check out our guide on how to choose your trail running shoes or browse our selection of high-performance trail shoes directly.
- Clothing: Avoid cotton — it holds sweat. Go for waterproof, breathable trail jackets to handle unpredictable mountain weather.
- Carrying: A well-fitted trail running vest is essential for carrying your hydration and emergency blanket without annoying bounce.
Expert tip: don't be afraid to walk!
In trail running, walking isn't failure — it's smart racing. Even elite champions walk the steep climbs to keep their heart rate in check. Saving energy on the way up means you can push much harder on the flat or downhill. Want to progress even faster? Try fast-hiking (active hiking) to build your aerobic base without the impact of running.
