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.
