Not to be outdone by the main event, a group of brave souls have stripped the Olympic Games right back to basics as they pay tribute to the ancient Greeks by staging their own games – in the nude.
The dedicated naturists are competing every weekend on a beach in Rio de Janeiro, in a series of high-spirited and energetic contests that toss all inhibitions out of the window.
The organisers say anyone can take part – as long as they are prepared to strip off.
Naked Olympic events include football, beach volleyball, swimming, race walking and sprinting – all conducted by stark naked competitors.
