So I was pleased to read today that Viviani has won the gold at the Rio Olympics in the "Omnium", a kind of cycling decathlon, or more accurately a sextathlon, since there are only 6 events rather than the decathlon's 10.
Very impressive ride for Italia. Some nice photos on the Reuters site, accompanying their report.
As for Cavendish, he seems to have a bit of difficulty following the rules. In one of the events he cut inside and rode below the inner boundary of the track to pass a group, resulting in a penalty. In another event, he swooped down and cut off a Korean rider causing a crash that eventually toppled other riders, including Viviani. Maybe if he had more practice on the track ... maybe if he had visited Shuzenji back in 2011?
