Florence Griffith-Joyner known as Flo Jo was one of the best female Olympic athletes ever. Her world records in the 100m and 200m dashes still stand today. She ran a whopping 10.49 in the 100 meters which is still the current world record giving her the title of "the world's fastest woman of all time". Carmelita Jeter is probably the fastest woman alive right now and will be going for her first Olympic gold medal in the 100m later today in the women's 100m final. As of right now though, Flo Jo remains the fastest woman ever.
