Great Britain & Northern Ireland came into the final weekend desperate to add to their solitary medal, provided by Farah with his 10,000m win on the opening weekend.
They look more than likely to fall well short of their 2015 tally of four while by contrast, the US have had a storming championships.
Before the final two sessions, they had already amassed eight golds in a total of 23 medals well clear of Kenya in second (three golds out of eight medals).
World Athletics Championships 2017 Day 9 results
(GB athletes in brackets)
5.30pm & 6.55pm Men’s javelin decathlon (Ashley Bryant)
Standings after nine events
1st Kevin Mayer (France) 8067pts, 2nd Rico Freimuth (Germany) 7894pts, 3rd Kai Kazmirek (Germany) 7796pts…15th Ashley Bryant (GB) 7286pts.
7.05pm Women’s high jump final (Katarina Johnson-Thompson & Morgan Lake)
Katarina Johnson-Thompson may only be 24, but she has already had a heck of a lot of nearly in her career.
Long dubbed the successor to Jessica Ennis-Hill as Britain’s star heptathlete, she failed to record a valid long jump two years ago and finished last in the event.
She was again left disappointed this time around after scoring just 700 points in the javelin and finish fifth.
But now she has just one event to concentrate on and qualified in good shape.
Team-mate Morgan Lake is also in lifetime best 1.96m form this year but Authorised Neutral Athlete Maria Lasitskene from Russia is a massive favourite with the only jump over two metres outdoors in 2017.
8.05pm Women’s 100m hurdles final
GOLD Sally Pearson (Australia), SILVER Dawn Harper Nelson (US), BRONZE Pamela Dutkiewicz (Germany)
Kendra Harrison needed a fastest loser’s spot to get through the semi-final after hitting the first hurdle and again showed little rhythm in the final.
Sally Pearson had been silky smooth through the heats and after missing the worlds two years ago and Rio last summer both through injury, she was not to be denied.
She never looked beatable and ran 12.59s to seal her country’s first gold of the championships.
8.15pm Men’s javelin final
Johannes Vetter’s 91.20m throw in qualifying was the longest ever at that stage of the tournament. The German looks ready to take his first ever global title after finishing fourth at the 2016 Olympic Games.
Only team-mate Thomas Rohler has also passed 90m this season and is expected to be his main challenger but Vetter looks more than ready to break the championship record of 92.80m and seal a momentous gold.
8.20pm Men’s 5,000m final (Mo Farah & Andrew Butchart)
No-one has ever done what Farah has done so far and won 10 straight global titles so this would be a mere extension of his record. But it remains hard to believe that he is such a huge favourite – surely, someone must find a way to undo him?
The Ethiopians of Muktar Edris, Yomif Kejelcha and Selemon Barega will work together to ensure the race is not left to a sprint finish Farah will always win but few have the kind of power the Brit possesses to strike from any distance.
8.45pm Men’s 1500m decathlon (Ashley Bryant)
9.30pm Women’s 4x100m relay final
Two years ago, the British quartet ran a national record of 42.10s to finish fourth in Beijing. That mark has been lowered to 41.77s as female sprinting in the country reaches an all-time high in terms of quality.
The US ran the world leading time in the heat while the Brits were the only other team under 42 seconds and should challenge for a medal, if not the gold.
9.50pm Men’s 4x100m relay final
Bolt out. He will run the final leg of the final race of the night and will surely be the first over the line to finish a glittering career in the way in which it was conducted – with gold.
The Brits were just 0.03s off the national record in qualifying and almost beat the Americans. France also performed well and should be there or thereabouts.
