Will Shelly Fraser repeat Bolt's glory?
Shelly-Ann Fraser Pryce of Jamaica is aiming to become the first woman to win three Olympic gold medals in the women's 100m, which starts on Friday 30 July at the Tokyo Olympic Stadium.
Fraser Pryce will be 34 years and 216 days old on the day of the women's 100m final (31 July). She can become the oldest Olympic gold medal winner in this event. The Jamaican sprinter won gold in the women's 100m at the Olympic Games in 2008 and 2012, and took bronze in 2016.
The 34-year-old can become the first athlete to win four Olympic medals in the women's 100m event.
Shelly Fraser shares the record of three Olympic medals with Merlene Ottey, a Jamaican/Slovenian sprinter, who took one silver and two bronze medals representing Jamaica. Fraser Pryce holds the record of four world titles in the women's 100m event: 2009, 2013, 2015, 2019.

Another Jamacian in the race is Elaine Thompson Herah. She won the 100m and 200m sprint double at the Olympic Games Rio 2016. Herah can become the fourth athlete to win two Olympic gold medals in the women's 100m, after Wyomia Tyus (USA, 1964 and 1968), Gail Devers (USA, 1992 and 1996) and Fraser-Pryce (2008 and 2012).
In each of the past five Olympic Games, the gold medal winning time was faster than in the previous Games. Herah's 10.71s at Rio 2016 was the second-fastest gold medal winning time in history, after Florence Griffith Joyner's (USA) 10.54s in 1988.
