Happy birthday today (Friday) to two Olympic champions born on the same continent exactly five years apart.
Athlete A was born 51 years ago today and won a silver medal at the World Championships a year before triumphing at the Olympics. This athlete broke the world record four times, always in the same city.
Athlete B was born 46 years ago today and has won more World Championship gold medals than any other athlete - man or woman - in that event. Also an Olympic gold and silver medallist and a WC bronze medallist, athlete B never broke the world record.
Both athletes are still among the all-time top 10 in their best events. Can you name today's birthday athletes?
