Justin Gatlin claims to have been asked to leave the Beijing World Challenge by event organisers.
The 33-year-old ran his fastest ever 100 metres at the opening Diamond League meet of the season in Doha last week, posting a time of 9.74 seconds – the joint-sixth-fastest of all time.
Gatlin, who has served two doping bans, had been due to race on Wednesday, but had initially raised doubts about his fitness arriving in China – subsequently declaring himself fit to compete.
“They didn’t have any respect for me so they said ‘you better leave’,” he said. “I was happy to stay. I was cramping a lot after the fastest my body has ever run.
“It’s crazy. I have no idea what they were thinking. I think they thought I wasn’t man enough and I might pull up in the race, or not finish it and then still ask for money.
“But I’m not a man like that. I’m not the kind of guy to cheat people of their money or let the fans down… that’s not what I do.”
