The k doesnt actually stand for kilometres, but for 1000. It is used for money aswell (or basicly anything that can be counted). I understand the confusion, since it becomes 1k (1000) meters and it is actually where the k in km stands for.
Think someone mentioned it above, but surely u can accept "100m relay" or "100 metre/meter relay"...it's very clear what we're trying to say, the "4X" part isn't necessary
No it is actually another name for it (unless you knew that already and made a joke, but you seemed genuinely em not really sure what to call the emotion/behaviour (especially in english) baffled by the suggestion perhaps)
There is modern pentathlon which includes things like fencing and horse riding, so that doesn't fit here. And the athletics pentathlon isn't at the Olympics.
Why do men have to do 110m hurdles when women do 100m hurdles? What difference does 10m make? Of all the gender-based distinctions here, that one seems the most odd/arbitrary.
Mainly because of the difference in strides, 110m lets the men's hurdles be spaced further apart due to the general height difference between men and women
I couldn't find the translations ^^
Great quiz tho :)
