In the athletics sprint, in order to play well in the final, staying in the preliminaries and semi-finals seems to be a choice that many people will make. However, in the women's 200m preliminaries for the Tokyo Olympics, Jamaican athlete Sherrika Jackson overturned. As the third runner-up in the 100 meters, she was overtaken by her opponent due to early deceleration, ranking fourth in the group with a gap of 0.04 seconds, and regrettably stopped in the first round.

Serika Jackson won a bronze medal by running her personal best of 10.76 seconds in the women's 100m final at the Tokyo Olympics. Along with teammates Elaine Thompson and Shelly Ann Fraser Price, she helped Jamaica finish in the top three of the 100m battle. However, in the 200m preliminaries, Serika was unfortunately out. In the sprint stage, she was in second place, taking the initiative to slow down, and she did not notice that the opponent behind her was very close to her. In the final result, she finished fourth with 0.004 seconds and was eliminated after advancing to fourth in the top three and three best-performing groups.
Fans in Jamaica were annoyed and said it was difficult to understand her behavior, bombarding her for her stupidity. Serika, who had the opportunity to hit the 200m gold medal or medal, could only be criticized. Sprint star Colin Jackson said: "She made a mistake and paid a high price. Originally one of the fastest 200-meter athletes in the world, now the spectators are missing out on a great contest. Jamaican sprint coach Stephen Francis explained: "Sherrica is not an experienced sprinter, she is a senior athlete in the 400 meters, but she is only a rookie for the 200 meters. I expect her to do better and she will learn more. ”
