Trail running pace calculator
Convert between pace, time and distance. Analyze your trail pace by section and generate a split table for your next race.
Typical trail running paces
Average pace by level
- Beginner: 9:00–14:00 /km
- Intermediate: 7:00–11:00 /km
- Advanced: 6:00–9:00 /km
- Elite: 5:00–7:00 /km
Road vs trail (same effort)
- 5:00 /km road ≈ 7:00–9:00 /km trail
- 6:00 /km road ≈ 8:00–11:00 /km trail
- 7:00 /km road ≈ 9:00–13:00 /km trail

Road vs trail pace comparison
Reference table showing approximate pace equivalences between road and trail running for different levels. Trail paces assume moderate elevation (~50 m D+ per km).
| Level | Road pace | Trail pace* | Factor |
|---|---|---|---|
| Beginner | 6:30–7:30 /km | 9:00–14:00 /km | ×1.4–1.9 |
| Intermediate | 5:30–6:30 /km | 7:00–11:00 /km | ×1.3–1.7 |
| Advanced | 4:30–5:30 /km | 6:00–9:00 /km | ×1.3–1.6 |
| Elite | 3:30–4:30 /km | 5:00–7:00 /km | ×1.3–1.6 |
*Trail pace varies significantly with elevation, terrain and distance. These are approximate values for races with moderate technical difficulty.

Frequently asked questions
What is a normal pace in trail running?
It depends heavily on elevation and terrain. As a general reference: beginners run 9-14 min/km, intermediate runners 7-11 min/km, advanced 6-9 min/km and elite 5-7 min/km. On flat terrain these paces are faster; with heavy elevation gain, much slower. Average pace on a trail with 2000 m elevation gain will always be slower than a road race of the same distance.
Why is my trail pace so much slower than on road?
Three main factors: elevation (climbing at 500 m/h equals about 22 min/km), terrain (rocks, roots and technical trails slow you 5-15%) and accumulated fatigue in ultras. That's why the concept of 'effort-km' is used: 1 km with 100 m of climbing equals 2 km on flat. A 42 km race with 3000 m D+ equals about 72 effort-km.
How do I calculate my uphill pace?
The most practical way is to use vertical speed (meters of elevation per hour). If you climb at 550 m/h and the average gradient is 20%, your horizontal speed is about 2.75 km/h, which equals ~22 min/km. Beginners climb at 350-450 m/h, intermediate at 500-600 m/h, advanced at 700-800 m/h and elite at 900-1100 m/h.
What are negative splits in trail running?
It means running the second half faster than the first. In trail running this is unusual due to fatigue, but a good strategy is to start conservatively to save energy. The split table in this calculator helps you plan sustainable paces from the start.
How do I interpret pace in a race with heavy elevation?
Average pace (min/km) is misleading in trail. It's more useful to look at vertical speed (m/h) for climbs and effort-km to compare races. A 7:00/km on a race with 2000 m elevation gain is a much bigger effort than the same pace on flat ground.
How do I use the split table during a race?
Print it or save it to your phone. Check at each kilometer or aid station if you're ahead or behind the plan. Allow a 3-5% margin for the unexpected. The elevation-adjusted paces help you go slower uphill and recover downhill without overdoing it.
What is the difference between pace and speed?
Pace (min/km) is the inverse of speed (km/h). Trail runners use min/km because it's more intuitive for planning: 'I need to run 7:30/km to finish in 5 hours'. Speed is used more in cycling and flat running. Formula: pace = 60 / speed.
How much slower am I on technical terrain?
As a reference: smooth trail +0%, technical (rocks, roots) +5%, mountain (uneven, exposed sections) +10%, skyrunning (ridges, scrambling) +15%. On very technical sections like the Aizkorri ridge at Zegama, the penalty can reach 20-30%.
How the pace calculator works
This calculator offers three tools to help you plan your trail running pace:
- Quick converter: converts between distance, time and pace. Enter any two values and get the third instantly. Useful for quick calculations before or after a race.
- Trail pace analyzer: breaks down your expected pace by section type (flat, uphill, downhill) considering elevation, terrain and your level. It also shows your road-equivalent pace — what flat road pace represents the same effort.
- Split table: generates a kilometer-by-kilometer pace table based on your target time. Print it or copy it for race day to track your progress at each kilometer.
The trail pace analyzer uses a three-component model: flat pace (based on your base running speed), climb pace (derived from vertical speed in m/h) and descent pace. Correction factors for terrain type and ultra fatigue are applied on top.
The road equivalent uses effort-km (distance + D+/100 + D-/300) to express your trail effort as an equivalent flat road pace. This helps you compare your trail performance with your road running times.
