“Staging finals in the morning was done at the request of the Rio 2016 Organising Committee and the Olympic Broadcasting Service, supported by the International Olympic Committee,” said IAAF competitions director Paul Hardy.
“Having finals in the morning will also ensure that we receive maximum visibility for athletics at the Olympic Games across all time zones.”
There is at least one final in all of the morning sessions. All five road events – the two marathons and the three race walk events – will be held in the morning sessions, although both 20km race walks will be in the early afternoon.
Other morning Rio 2016 athletics finals include: women’s 10,000m, men’s and women’s 3000m steeplechase, men’s 400m hurdles, men’s triple jump, men’s and women’s discus, and the women’s hammer.
The IAAF also reiterated that "no credence whatsoever should be given to recent unfounded speculations regarding possible changes to athletics’ programme within the Olympic Games."
"While the Olympic Agenda 2020 recommendations were passed at last week's session, no details or specific proposals have yet been made by the IOC as to how they will be implemented."
