The first medal to change hands at the Rio Games for doping has placed further doubt on weightlifting’s credibility as an Olympic sport.

Usain Bolt lit up Moscow in the same manner as the real lightning bolts in the Russian skies as the mercurial Jamaican claimed his fourth global 100m title in the Luzhniki rain this evening.

Olympic champion Usain Bolt was unable to claim victory in his first Diamond League race of the season as Justin Gatlin continued his impressive form by edging out the Jamaican to win the 100 metres in Rome.

Yohan Blake and Usain Bolt were again the star attractions at a cold and drizzly Diamond League meeting in Zurich.

Allyson Felix was able to put the disappointment of two consecutive silver medals in the women’s 200 meters to claim the gold medal she so desired last night.
