The track and field drama will reach fever pitch at the Rio 2016 Olympics on Sunday evening, where the men's 100-metre final lights up a glittering evening of sport in Brazil's capital.
Some of the most anticipated medals on offer will be up for grabs at the Olympic Stadium, with Jamaica superstar Usain Bolt looking to become the first sprinter ever to win three 100-metre Olympic gold medals in succession.
The drama doesn't end there, though, as the final of the women's triple jump takes place shortly before the men's 400-metre final, not to mention the climaxes of the women's 3,000-metre steeplechase and hammer throw.
