How these numbers were computed
These are times for runners who finished. They exclude everyone who started and did not, so they describe how long finishing took, not how long the race takes. Bands with only a handful of finishers move a lot from one edition to the next.
We plot the median, not the average. A handful of very quick runners drags the average well below the time half the field actually beat, so the median is the honest number to plan against.
Nationality here shows who travels to this race, not who runs it best. That alone is why a host nation tops almost every list.

Ask the course
Ask EcoTrail Paris 120 anything about climbs, pacing, crew or cutoffs.
Answers come from this course's data, your plan and your training.
Which climb should I respect most?
Château de Dampierre to Château de la Madeleine: +363 m over 13.3 km, from km 41.6. Hike the steep sections at an effort you could hold for hours - the race is decided after this climb, not on it.
Where can my crew meet me?
Etangs de Hollande, km 16.7 - the first of 7 crew points. The next is Château de la Madeleine, km 54.9. Have them bring warm layers: the course tops out at 181 m, through the night, in March.
Is 16h a realistic finish for me?
16h would put you in the faster half of 2026 finishers - the median was 16:45:24. It means holding 8:00/km overall.
