Making most of our stadia

Hosting world-class sports events in magnificent stadiums doesn't come cheap.

The world is littered with once-spectacular stadia that were summarily abandoned after serving their purpose - left to rust into obsolescence. Many of the venues used for the Rio and Athens Olympics, for example, now lie idle as monuments to waste.

China, though, has been successful in bucking that trend, with the Shanghai International Circuit (SIC) Formula One track a shining example.
