Usain Bolt Retains His 100m Gold Medal At Rio Olympics

 

Usain Bolt claimed a record third 100m title while tennis player Andy Murray won Britain's fifth Rio gold medal on GB's best day at an overseas Olympics.
Bolt, 29, ran 9.81 seconds to beat Justin Gatlin to gold and follow up his titles at Beijing 2008 and London 2012.
"I expected to go faster, but I'm happy I won," he said. "I did what I had to."

Wimbledon champion Murray, 29, retained his Olympic title with an epic four-set win over Argentina's Juan Martin del Potro.
