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 Canyons 25K 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?
No Hands - 1 (Hydration) to Cool - 1: +352 m over 4.8 km, from km 5.6. 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?
No Hands - 1, km 5.6 - your first checkpoint, and no crew can meet you there or further on: the organiser lists no crew access on Canyons 25K.
Is 3h a realistic finish for me?
3h would put you in the faster half of 2026 finishers - the median was 3:31:05. It means holding 7:12/km overall.
