Traaaackkkk (Phrase) - Whenever you hear the phrase "Track" yelled at you while you are walking on a track, that means get out of the way immediately. There is a runner(s) quickly approaching behind you and they are trying to get your attention, so you don't get trampled.

Pro tip: If you are on the inside lanes of the track, move quickly to the left to get off the track and vis versa if you are on the outside lanes of the track.
