The 2016 Summer Olympic Games begin on Friday, as Rio de Janeiro, Brazil hosts the world's favourite sporting event.
A glittering opening ceremony will precede a cacophony of events, as the world focuses on the stars of track and field and a number of niche sports that operate under the Olympic banner.
Medals will be awarded for the best performing athlete or team in each category, with the winners taking away the prestigious gold back to their homeland.
The St. Louis 1904 Games in the United States was the first Olympic showcase to award gold, silver and bronze medals to highlight the achievements of the top three competitors.
