American Justin Gatlin stepped up his preparations for the Rio Olympics with an impressive victory in the 100 metres 14 May at the season’s second Diamond League meeting, in Shanghai, China.
Gatlin, who has twice served bans for doping, was unbeaten at 100 and 200 metres in 2015 until he faced an out-of-form Usain Bolt in the world championships in Beijing last August.
Bolt, the Olympic champion, won both the races but Gatlin showed in Shanghai that he was gearing up to challenge the Jamaican again at the Rio Games in August.
Gatlin led from the start and won in 9.94 seconds with Qatar’s Femi Ogunode — the quickest over 100 metres this year with 9.91 in Florida last month — finishing second in 10.07. Gatlin’s time is the second-fastest time of the year.
