Why does the 100m race hold the most significance amongst other races such as the 100 m hurdles or the 200 m?

Question

Why does the 100 metres race seem to be more significant than other races?

Why not long distance running?

Answer 1

its pure all out speed. any longer races involve some kind of strategy, holding off your full effort until near the finish. the 100m is just 100% effort for 10 seconds.

that, and its very short and easy to watch and understand whats going on . The average spectator wont sit through a 2 hour plus marathon.

Answer 2

It's the basic unit of pure athleticism. No equipment, no complicated rules, no teammates, just an athlete and his own body competing against others.
