Happy 57th birthday today (Monday) to an Olympic champion with two Olympic gold medals.

Both gold medals came with Olympic records.

This champion also won a World Indoor gold medal, a World Cup gold medal, and a World Championship bronze medal.

The first Olympic gold medal our birthday athlete won came on a Monday in the same continent in which this person was born.

You might already know that this individual was ranked number one in the world for four years by Track & Field News.

Did I tell you that this athlete also set a new world record?

Please name this Olympic champion with a birthday on the last Monday of August.
