"TT" can refer to various concepts, but one common meaning is "table tennis," a fast-paced sport played on a rectangular table divided by a net. Players use small paddles to hit a lightweight ball back and forth, aiming to score points by making the ball land on the opponent's side of the table. The game is popular worldwide and is governed by the International Table Tennis Federation. Another interpretation of "TT" is "time trial," a racing format where participants compete against the clock rather than each other. Time trials are common in cycling and running events, where athletes aim to achieve the fastest time over a set distance. This format emphasizes individual performance and strategy, often leading to exciting competitions.
