Times stated are local (BST) and were correct at the time of publication.
10:00 – Decathlon 100m
There are four heats.
Britain’s Ashley Bryant goes in heat 2 alongside Olympic silver medallist Kevin Mayer. The 2015 runner-up Damian Warner and two-time champion Trey Hardee in heat 4 have the fastest PBs.
10:10/11:35 – Women’s discus qualifying
62.50m or top 12 is required to make the final. Double Olympic champion Sandra Perkovic is in Group 1 alongside Olympic champion Denia Caballero and Britain’s Jade Lally.
10:45 – Women’s 100m hurdles heats
The first four in each of the five races advance alongside the next four fastest.
Defending champion Danielle Williams goes in heat one alongside GB’s improving Alicia Barrett. The 2013 bronze medallist Tiffany Porter goes in heat two alongside USA’s Nia Ali.
World record-holder Kendra Harrison goes in heat three. The 2008 Olympic champion Dawn Harper Nelson goes in heat four against 2012 Olympic champion Sally Pearson. USA’s Christina Manning heads heat five contenders
11:05 – Decathlon long jump
Eight metre jumper Damian Warner should increase his lead, while Bryant should move up.
11:15 – Men’s high jump qualifying
The advertised qualifying height is 2.31m which seems unlikely. Mutaz Essa Barshim and Bohdan Bondarenko are favourites while 2012 bronze medallist Robbie Grabarz should qualify.
12:55 – Decathlon shot put
17:00 – Decathlon high jump
19:05 – Women’s 100m hurdles semi-finals
There are three semi-finals with the first two, and the next two fastest, going into the final.
The first semi features the 2012 Olympic champion Sally Pearson, the Olympic silver medallist Nia Ali and Jamaican Megan Simmons.
The second semi should be between defending champion Danielle Williams and American Christine Manning. Others who should challenge are 2015 world bronze medallist Alina Talay and Jamaican former world youth champion Yanique Thompson.
The final semi will surely be dominated by Keni Harrison, who set the world record on this track last year.
The world-leader should be followed home by 2008 Olympic champion Dawn Harper-Nelson or Germany’s Pamela Dutkiewicz.
Teenager Rushelle Burton, who was second in last year’s world junior championships, is another possible challenger.
19:10 – Women’s long jump final
Olympic and world champion Tiana Bartoletta and three-time former champion Brittney Reese are favourites.
Ivana Spanovic, who has won medals in the last five global championships she has contested – indoors and out, may not be in her best form.
Lorraine Ugen, who was second to the Serbian in the European Indoors Championships this year, has the potential of a medal.
Others who should challenge are Germany’s Claudia Salman-Rath and Russian Darya Klishina, who is competing as a neutral.
19:35 – Women’s 800m semi-finals
The first two in three semi-finals and the two next fastest qualify for final.
American champion Ajee Wilson is favourite for the first semi. The other potential qualifying spots look to be between world silver medallist Melissa Bishop and Cuban Rose Almanza and Ethiopian Habitam Alemu. Even a big PB might not be enough for Adelle Tracey to progress.
Lynsey Sharp looks like she has a task to repeat her Rio feat of making the final.
Olympic champion Caster Semenya should win easily with European indoor champion Selina Buchel, American Charlene Lipsey and fast-finishing Angelika Cichocka likely to contest second with Sharp.
The third semi-final see Shelayna Oskan-Clarke up against Rio medallists Francine Niyonsaba and Kenyan Margaret Wambui to make the final. The Briton plus USA’s Brenda Martinez may have to rely upon a fastest losers spot to get through.
20:10 – Men’s 1500m semi-finals
The first five in two semi-finals and the two fastest losers qualify.
Jake Wightman is in the first semi-final against world-leader Elijah Manangoi, Olympic medallist Abdalaati Iguider and defending champion Asbel Kiprop.
Bahrain’s Sadik Mikhou, who has run 3:31.34 this year, should also qualify.
European champion Filip Ingebrigtsen and Australian heat winner Luke Mathews also feature. Mathews said he had benefitted in recent weeks from advice from Jake’s father Geoff, who is doing the announcing in the stadium.
The second semi-final features Britain’s 2013 finalist Chris O’Hare up against Timothy Cheruiyot and double Olympic medallist Nick Willis plus world junior record-holder Ronald Kwemoi. The Czech Jakub Holusa, European indoor champion Marcel Lewandowski and German Homiyu Tesfaye could all be in danger in a slow-run race.
20:30 – Men’s hammer final
Defending champion Pawel Fajdek is a big favourite along with team-mate Wojciech Nowicki and Olympic champion Dilshod Nazarov.
The battle for medals is open though and could go any one of ten ways.
Nick Miller was 11th in 2015, which is the UK’s highest ever world placing, and he is capable of greatly improving that.
AW prediction last week: 1 Fajdek; 2 Nowicki; 3 Nazarov.
This week: 1 Fajdek; 2 Nowicki; 3 Nazarov; 4 Pronkin; 5 Bareisha; 6 Halasz; 7 Marghiev; 8 Bigot; 9 Miller; 10 Sokyrskii; 11 Lingua; 12 Baltaci.
20:45 – Decathlon 400m
Britain’s Bryant goes in heat two. Decathlon 100m winner Warner, who has a 46.54 PB, goes in heat four.
21:25 – Women’s 3000m steeplechase final
Judging by the Diamond League races, this could be an open race.
World record-holder and Olympic champion Ruth Jebet has not looked as dominant this year.
Likely to challenge the Bahraini are her former compatriots world junior record-holder Celliphine Chespol, Commonweath champion Putity Kirui, Olympic fourth-placer Beatrice Chepkoech and defending champion Hyvin Jepkemoi.
The best of the rest are probably 2015 world bronze medallist Gesa-Felicitas Krause and Rio bronze medallist Emma Coburn.
AW prediction last week: 1 Jepkemoi; 2 Jebet; 3 Chespol.
This week: 1 Jepkemoi; 2 Jebet; 3 Krause; 4 Chespol; 5 Coburn; 6 Chepkoech; 7 Kirui; 8 Diro; 9 Lacaze; 10 Fente; 11 Lalonde; 12 Praught; 13 Yavei; 14 Frerichs; 15 Casetta.
21:50 – Women’s 200m final
The lane order is Canada’s Crystal Emmanuel (PB 22.50), Tynia Gaither of Bahamas (22.54), 100m runner-up Marie-Josée Ta Lou (22.16), Olympic 400m champion Shaunae Miller-Uibo (21.91), defending champion Dafne Schippers (21.63), American Deejah Stevens (22.09), Rio and Beijjing fifth-placer Dina Asher-Smith (22.07) and Kimberlyn Duncan of the USA (22.19).
Schippers starts as marginal favourite but the other semi-final winners Ta Lou and Miller-Uibo ran near identical times then and look evenly matched. Asher-Smith could repeat her recent fifth places, despite not being in peak shape yet after injury.
AW prediction last week: 1 Bowie; 2 Schippers; 3 Miller-Uibo.
Prediction this week: 1 Schippers; 2 Miller-Uibo; 3 Ta Lou; 4 Stevens; 5 Asher-Smith; 6 Duncan; 7 Gaither; 8 Emmanuel.
