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 100M 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?
China Wall to Deadwood - 1: +671 m over 18 km, straight from the gun. 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?
Michigan Bluff, km 36.4 - the first of 5 crew points. The next is Foresthill, km 45.9. Have them bring warm layers: the course tops out at 1,529 m, through the night, in April.
Is 31h a realistic finish for me?
31h would put you in the faster half of 2026 finishers - the median was 31:07:23. It means holding 11:33/km overall.
