The phrase they are off has long been used by race announcers to mark the instant a field leaves the start, and it carries that same instant-start feeling when it is clipped for short video. Creators reuse it because it needs no explanation: the countdown builds tension and the final words release it in one beat. That clarity has kept it popular for race edits, challenge openings, reaction clips and countdown compilations, where a recognisable start signal works better than a generic beep or horn.

A race announcer counts down 3, 2, 1 before shouting they are off, the classic start signal for races used to kick off videos, streams and challenges.
This short clip captures the moment a race gets underway, with a clear announcer voice counting down three, two, one before delivering the punchy declaration that they are off. The delivery is brisk and excited, rising in energy through the countdown and landing with a burst of momentum on the final phrase. It lasts just a few seconds, which makes it feel urgent and decisive rather than drawn out. For a viewer, it instantly creates a sense of anticipation followed by release, as if a starting gate has just opened and everyone is suddenly in motion.
