• Event arranged to fine-tune Covid protocols ahead of Games
• Coe pledges to ‘deliver events in a safe and secure environment’

Hundreds of athletes including the US sprinter Justin Gatlin participated in a test event at Tokyo’s Olympic Stadium on Sunday as organisers fine-tuned operations and Covid countermeasures with under three months to go before the Tokyo Games.

No spectators were present in the stadium, where the opening and closing ceremonies will be held, as Tokyo remains under a state of emergency because of a rise in coronavirus cases.
