@DaLJBeast is the Twitter handle of Brittney Reese.

Defending champion Kirani James and Beijing 2008 Olympic champion LaShawn Merritt remain on course for what seems an inevitable head-to-head battle for the gold medal after both came through comfortably in the first round of the men s 400m.

Sandra Perkovic made history inside the Luzhniki Stadium by becoming the first woman to complete the ‘Grand Slam of Olympic, European and World Discus titles with a typically dominant performance.

The two fastest women in the world this year did the bare minimum required to win their 100m heats; in stark contrast, USA s English Gardner sped to the fastest first-round clocking ever at the World Championships.

Was there ever any doubt that Brittney Reese would win an unprecedented third gold medal in the women s Long Jump at the IAAF World Championships?

Just like at the IAAF World Championships in Daegu two years ago, the longest race on the track boiled down to a last-lap battle between Great Britain s Mo Farah and Ethiopia s Ibrahim Jeilan, but this time the roles were reversed.
