More medals are on offer in track and field, with the men's 400m and women's pole vault, where Holly Bradshaw will compete for her first major podium finish.
The athletics sees medals given in the women's pole vault, men's 400m, the women's heptathlon and the men's decathlon, plus the 4x400m women's relay heats and men's 1,500m semi-finals.
GB's Holly Bradshaw is looking to secure her nations first ever medal in the pole vault. The Brit finished sixth at London 2012 and fifth in Rio 2016 but will be looking to better that performance in what will be a close final. The Russian Olympic Committee's Anzhelika Sidorova will be favourite with the world number one tag looking over her, but Bradshaw will need to see off the likes of Nageotte of the US and Stefanidi of Greece.
GB's women are looking to progress through the heats of the 4x400m heats. The Brits are up against the might of the US and Jamaica but with the first three in each heat qualifying for the final, they have a good chance of progressing. Emily Diamond, Zoey Clark, Laviai Nielsen and Nicole Yeargin were looking to run as close to sub 51 seconds per leg as possible to guarantee an automatic qualification spot.
The men are in the closing stages of the decathlon competition with the conclusion of the javelin, as well as the final event in the 1,500m. World number one Damian Warner is leading coming into the final session and he is looking to break the magical 9,000 point mark, and smash the Olympic record. The battle for the other two medals is on with the likes of Kevin Mayer of France, Garrett Scantling of the US and Ashley Moloney of Australia in contention.
GB's Jake Wightman is looking to make the final of the men's 1,500m alongside fellow countrymen Josh Kerr and Jake Heyward. Favourite, Abel Kipsang of Kenya, will no doubt go out looking to cement his intentions in his semi-final but the Brits will be well in the mix across the two semi-finals. The top five from each race, plus the next two fastest times, qualify for Saturday's final.
There is a gold medal to be had in the men's 400m final. Kirani James breezed through his semi-final but will come up against Steven Gardiner of the Bahamas and Anthony Jose Zambrano of Columbia in the fight for gold. There is no British representation in this final but look out for the two American athletes, who will be knocking on the doors for medals.
Katarina Johnson-Thompson was out of the heptathlon leaving favourite Nafissatou Thiam in pole position to take the gold. The medals would be awarded in this session as the athletes conclude their competition with the 800m. Hot on Thiam's heels are fellow countrywoman Noor Vidts and Dutch duo Anouk Vetter and Emma Oosterwegel. There are a trio of American competitors looking to break into the top ten, too.
