Gold panning
Host nations always do well in the Olympics: Great Britain won its largest bounty of modern times at the 2012 Games, China topped the table for the first time in 2008 and Greece broke its own modern-day record in 2004, winning six golds. Brazil, though, may not hit those heights. So far the South American hosts have bagged just three golds – two down on its 2004 record haul. Beach volleyball is still to come but Brazil may pay for its failure to win more judo medals last week. At least the country has a new sporting hero to celebrate: pole vaulter Thiago Braz da Silva won an unexpected gold in the Olympic stadium on Monday night.
