Racing can be pictured as two or more things setting off at the same moment, where the only question that matters is who gets there first. It does not matter what they are — runners, horses, bikes, boats, even small flying machines. Once speed is the point, the word fits, and everything else in the entry is either that activity or something built to take part in it.
From the word’s history
The supplied Wiktionary entry analyses the word on the surface as race + -ing: the -ing form of the verb race, used as the name of the activity.
來源的 Wiktionary 把這個字拆成 race + -ing，也就是動詞 race 的 -ing 形式。-ing 把一場一場的比賽收成一項活動的名字，所以才會有 motor racing、horse racing 這樣的組合。
Wiktionary (kaikki extract 3f6f69a190036ae4), entry 'racing': 'By surface analysis, race + -ing.'
