TRAIL TIMES
How long does a 160 km trail take?
On a 160 km trail, finish time depends far more on elevation gain than on distance. For a typical course around 9000 m of D+ (250 effort-km), expect the ranges below by level. Weather, terrain technicality, heat and race-day form can shift the result by ±15%.
Very long ultras (120 km and up) are 18 to 40 h adventures: 6 months or more of prep, one or two nights, crew and drop bags, and a strategy where finishing beats the clock.
Indicative time over 160 km (~9000 m D+)
| Level | Estimated time |
|---|---|
| Beginner | 32h10 – 41h05 |
| Regular | 26h10 – 33h25 |
| Experienced | 22h05 – 28h10 |
| Elite | 18h25 – 23h35 |
Indicative ranges based on effort-km. Your real D+ and profile change everything: use the estimator for a precise figure.
Elevation gain changes everything
At equal distance, D+ blows up the clock. For a regular runner over 160 km:
Rolling profile
~5000 m D+
24h25
Mountain profile
~11000 m D+
31h25
How this time is calculated
We use effort-km: effort-km = distance + D+ / 100. Each level covers a given amount of effort-km per hour. It's a robust benchmark, but a real estimate compares your ITRA, UTMB or B-Trail index to actual finishers — that's what our estimator does. Glossaire.

FAQ
What is the average time for a 160 km trail?
For a course around 9000 m of D+, a regular runner usually takes 26h10 – 33h25. A beginner will be closer to 32h10 – 41h05, an experienced runner around 22h05 – 28h10.
What pace should I hold on a 160 km trail?
In trail running we think in effort-km rather than raw pace: here about 250 effort-km. On flat, rolling sections pace nears road running; as soon as it climbs, power-hiking takes over.
How much elevation gain on a 160 km trail?
It varies wildly: from about 5000 m of D+ on a rolling course to 11000 m on a mountain route. The average sits around 9000 m.
How do cut-off times work on a 160 km trail?
Each organiser sets deadlines at checkpoints. Aim for a comfortable margin over your «conservative» time: that's exactly what the estimator computes, aid station by aid station.
How long does it take to train for a 160 km trail?
It depends on your base, but aim for the order of magnitude shown above for this distance category, with a progressive build-up and at least one long run representative of the D+.
