(CNN)In just one week, the eyes of the world will be on Rio de Janeiro as the Olympic Games arrive in South America for the first time.
The build up to Rio 2016 has been beset by political, economic and health crises, while doping has cast a shadow over sport and track and field in particular.
On August 5, organizers will hope to put all those various problems behind them when athletes from across the world march into the Maracana Stadium for the Opening Ceremony and the lighting of the Olympic cauldron.
Here’s how we stand as the countdown to the world’s biggest sporting event enters the home straight.
Most Olympic Games face questions over whether they are really worth the money. Billions of dollars are invested in redeveloping the infrastructure of host cities, but just what is the legacy from these sporting jamborees that are held every four years?
“In its favor Rio has avoided expensive iconic architecture, opting for the dull, the functional and the temporary,” said author David Goldblatt, who has written a history of the Olympics, in the Guardian this week.
“Consequently it is set to produce fewer and less expensive white elephants than the leaders in this field, Athens (2004) and Beijing (2008).”
