The delayed Olympic Games in Tokyo will see 339 medal events crammed into a 19-day period, with two sports kicking off before the opening ceremony.
This is to ensure all the longer events can be crammed in before the closing ceremony on August 8 as well as making sure there are no significant clashes on TV.
