In the 28-person men's 100 meter race, the grouping, admission and arrangement of each race were arranged.

Generally speaking, 28 people draw lots to decide the order of the game. Usually, they run to a group of eight people. 1~8, 9~ 16, 17~24, 25~28 can be divided into four groups (the first three groups have 8 people, and the last group has 4 people, which is completely fair and reasonable because the order is determined by drawing lots.
