The area that is next to a track, often found at a racetrack or similar locations.
The spectators gathered trackside to watch the race.
Trackside → It is formed from "track" (from Old English *trac*, meaning a path or course) and "side" (from Old English *side*, meaning the lateral part of something). The word "trackside" refers to the area located beside a track or path.
Think of a 'path' ('track') and the 'lateral part' ('side') next to it — that's what trackside means.
