On the eve of the Games we gather our predictions from our detailed previews, updated with any late additions we know of though we are still not 100% sure what events the likes of Sifan Hassan and Shaunae Miller-Uibo will line up for!
The selections are based on a mixture of current form, previous championships records and knowledge of any recent injuries with a slight reference to World Athletics rankings system.
We predict the United States will easily top the medals table with 13 golds, 12 silvers and 8 bronzes which is similar to Rio (13, 10, 9) but would be their best since the boycotted Games of Los Angeles in 1984 (16, 15, 9), although the best in a fully contested Games since Mexico in 1968 (15, 6, 7).
We expect Kenya (5, 2, 3) to win a battle with Jamaica (3, 5, 1), Ethiopia (3, 4 1) and Poland (3, 0, 0) for second spot in the medal table.
On our predictions, we estimate Britain won't make the top 20 in the medals table due to a possible lack of golds but only four countries will get more medals than Britain.
We are estimating seven bronzes (two for Dina Asher-Smith, two for sprint relays, plus Laura Muir, Holly Bradshaw and Josh Kerr) but there are quite a few expected top sixes and certainly at least a dozen medal chances.
100m:
Will be closer and slower than Bolt's 2008 and 2012 wins but the American stands out.
