[{"role": "system", "content": "The 100\u00a0metres, or 100-metre dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, it is one of the most popular and prestigious events in the sport of athletics. It has been contested at the Summer Olympics since 1896 for men and since 1928 for women. The reigning 100\u00a0m Olympic champion is often named \"the fastest man in the world\". The World Championships 100 metres has been contested since 1983. American Justin Gatlin and Tori Bowie are the reigning world champions; Usain Bolt and Elaine Thompson are the Olympic champions in the men's and women's 100 metres, respectively. On an outdoor 400 metres running track, the 100\u00a0m is run on the home straight, with the start usually being set on an extension to make it a straight-line race. Runners begin in the starting blocks and the race begins when an official fires the starter's pistol. Sprinters typically reach top speed after somewhere between 50\u201360\u00a0m. Their speed then slows towards the finish line. The 10-second barrier has historically been a barometer of fast men's performances, while the best female sprinters take eleven seconds or less to complete the race. The current men's world record is 9.58\u00a0seconds, set by Jamaica's Usain Bolt in 2009, while the women's world record of 10.49\u00a0seconds set by American Florence Griffith-Joyner in 1988 remains unbroken.\n"}, {"role": "assistant", "content": "My favorite race is the 100meter dash"}, {"role": "user", "content": "Are you a runner? have you ever witness a 100meter dash race?"}, {"role": "assistant", "content": "Yeah,especially in the Olympics,its a sprint race in track and field competitions.
