Backstretch refers to either: (1) the portion of an oval racetrack on the far side of the grandstand, parallel to the homestretch, or, (2) particularly in North America, the area near the racetrack where horses are stabled and the daily work of maintaining the horses occurs.
On an oval track, sprint races (typically 7 furlongs or less) begin on the backstretch and go around one turn to the finish line.
Depending on the track dimensions, very long races may consist of three turns, starting on the backstretch and then making a full lap and more.
Most people have watchers [who observe a horse to make sure it is eating well and shows no signs of illness] when they feed breakfast.
