The classification of difficulty levels in trail running routes is based on several key parameters:

• Route distance

• Terrain type – including surface conditions, natural obstacles, etc.

• Elevation changes – steep ascents and descents

• Navigation – the complexity of route finding

• Required technique – technical running, jumping, balance, etc.

• Logistical aspects – accessibility, water stations, trail markings, and more

Of course, difficulty is also a personal matter – each runner should take into account their own fitness level and experience when choosing a route.

🟢 Level 1 – Easy

Suitable for anyone who can run more than 5 km. Walking sections are always an option in more challenging parts.

• Distance: Up to 5–8 km

• Terrain: Flat or gently rolling, on well-compacted dirt roads or wide forest paths

• Incline: Up to 5–10%

• Navigation: Easy, well-marked trail

• Focus: Pleasant running, open landscapes, no technical obstacles

🟡 Level 2 – Moderate

For runners with a basic fitness foundation, looking for a mild challenge.

• Distance: 8–15 km

• Terrain: Mix of wide trails and singletracks, with roots/stones

• Incline: Sections with 10–20% grades

• Navigation: Marked, but requires attention or basic app navigation

• Focus: Building endurance, basic technical awareness

🔴 Level 3 – Hard

For experienced trail runners with good physical and technical ability.

• Distance: 15–30 km (or shorter routes with cumulative difficulty)

• Terrain: Technical singletracks, rocks, mud, roots, scree

• Incline: Steep sections, over 20–30%

• Navigation: Complex, requires GPS or prior experience

• Focus: Significant physical and mental challenge, proper gear required

⚫ Level 4 – Very Hard (Extreme)

For elite runners only – highly challenging routes.

• Distance: Over 30 km or shorter with extreme difficulty

• Terrain: Includes hand-assisted climbs, water crossings, rapidly changing terrain

• Incline: Sharp and sustained elevation changes

• Navigation: Self-navigation, critical, often with no clear markings

• Focus: Maximum endurance, emergency gear, deep understanding of terrain and conditions
