Running Towards Gender Equality
At the Rio 2016 Olympics 15 out of 28 sports had less than 50% female athlete representation. For Tokyo 2020, countries will be required to be represented by at least one female and one male athlete overall and numerous sporting codes, such as Rowing and Weightlifting, will be moving to equal numbers of events and athlete quotas at the Olympics based on gender.
