Medal events in archery, cycling, fencing, judo, taekwondo and weightlifting will also be held, with medals being awarded in a total of 11 events on the same day.

The finals of nine athletics events will also be held in the morning, along with medal rounds in basketball, beach volleyball and swimming.

The start times of both men's and women's marathons are scheduled one hour earlier than usual, at 6am local time, in order to reduce the possible influence of summer heatwaves.

"Super Saturday" and "Golden Sunday", August 1 and 2 respectively, are expected to attract huge stadium audiences and TV viewers around the world, with a large number of medal events scheduled to be held, organizers said.
