About 11 h for a mid-pack finisher (index 500). Not a pacing guarantee.

Men and women

Two medians on the same scale. The bars run from the start to the cutoff, so the gap between them is the gap in time.

Finish time by age group

Every track runs from the start to the 29h cutoff, so the empty part of a bar is the time that group's median finisher still had. Men and women are drawn on the same scale.

Edition by edition

Every edition we have recomputed in full, newest first. The course, the weather and the field change from year to year, so a slower edition is not a harder one.

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 Javelina 100K 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?

Assistant From course data

Coyote Camp (loop 2) to Jackass Junction (loop 2): +275 m over 10.5 km, from km 42.3. 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?

Assistant From course data

Javelina Jeadquarters, km 35.9 - your only crew point.

Is 16h a realistic finish for me?

Assistant

16h would put you in the faster half of 2025 finishers - the median was 16:57:02. It means holding 9:46/km overall.

A barrier is a cut-off to clear, not a pace to aim for: race on effort, and expect the later legs to be slower.
