The arrangement of all that athletics action was altered today following forecasts of rain and high winds - likely to be blowing into the faces of the sprinters - on Saturday.

Accordingly the men's pole vault, featuring Olympic gold and silver medallists Mondo Duplantis of Sweden and Chris Nilsen of the United States, the women's discus, featuring the US Olympic champion Valarie Allman, and the women's high jump, involving Ukraine's world indoor champion Yaroslava Mahuchikh, have been moved to Friday night's programme, where world record attempts are being made over two miles and 5,000 metres.

The news that the United States' Olympic women’s 800 metres champion Athing Mu will not now race against Britain’s Tokyo 2020 silver medallist Keely Hodgkinson, and that Italy’s men’s 100m champion Marcell Jacobs will not be in a field including the man he beat to gold in Japan, home sprinter Fred Kerley, was disappointing.

Also missing from the planned line-up at the new-look Hayward Field, which will stage this year’s World Athletics Championships, are home talents Matthew Centrowitz, the Rio 2016 1500m gold medallist, Tokyo 2020 and world 400m hurdles silver medallist Rai Benjamin and double world pole vault champion Sam Kendricks.

And South Africa’s double Olympic 800m champion Caster Semenya, who had planned a first top-level race since 2019, has also withdrawn.

All this means the limelight will shine all the more intensely on stellar performers such as Jamaica’s double Olympic women’s 100 and 200m champion Elaine Thompson-Herah, who runs over the shorter sprint against a field including the American who missed last year’s Olympics because of a three-month suspension after testing positive for cannabis, Sha’Carri Richardson.

Britain’s world 200m champion Dina Asher-Smith, who last Saturday won the Birmingham Diamond League 100m from which Thompson-Herah had made a late withdrawal, is also in the mix, as is Switzerland’s world indoor 60m champion Mujinga Kambundji and Jamaica’s Tokyo 2020 bronze medallist Shericka Jackson.

Thompson-Herah chose to make a low-key start to her outdoor season, choosing to compete in Kingston, where she clocked 10.94sec despite a strong headwind of -1.8 metres per second.

It was on this track last year that she ran 10.54, putting her second on the all-time list.

The men’s 100m is also loaded given the presence of Kerley and his fellow Americans Trayvon Bromell, who will be keen to restore normal working after his early exit in Birmingham because of a false start, world champion Christian Coleman, world 200m champion Noah Lyles and Canada’s Olympic 200m champion Andre De Grasse.

And 18-year-old Erriyon Knighton, who last year became the youngest male athlete to represent the United States since middle distance runner Jim Ryun in 1964 and missed a 200m medal by one place, will seek to break 10sec for the first time.

Knighton already tops this year’s 200m world list with his startling 19.49sec in Baton Rouge last month, which put him fourth on the all-time list.

The women’s 200m will see double Olympic 400m champion Shaunae Miller-Uibo taking on Jamaica’s 35-year-old Beijing 2008 and London 2012 100m champion Shelly-Ann Fraser-Pryce, who won world gold at this distance in 2013 and took silver at the London 2012 Olympics.

The men’s 400m will see Kirani James of Grenada, the London 2012 champion and Tokyo 2020 bronze medallist, take on home athletes including Michael Cherry, Michael Norman – a major talent currently seeking a performance to do himself justice - Vernon Norwood and Kahmari Montgomery.

The absence of Benjamin from the 400m hurdles will offer Brazil’s Tokyo 2020 bronze medallist Alison Dos Santos - who beat Benjamin in the opening Diamond League meeting of the season in Doha – a perfect chance to shine,

In the women’s 100m hurdles, Puerto Rico’s Olympic champion takes on the American who took silver behind her in Tokyo, world record holder Kendra Harrison.

The traditional Friday evening distance racing in Eugene will include a women’s two miles and a women’s and men’s 5000m race.

At the latter, which will be followed by an official Diamond League 5,000m on Saturday, Uganda’s Joshua Cheptegei is billed to make an attempt at breaking his own world record of 12min 35.36sec, which he ran in Monaco in August 2020.

On Saturday afternoon the majority of the rivals Cheptegei beat to win Olympic 5,000m gold in Tokyo last year will line up for the Diamond League 5.000m, where Olympic 10,000m champion Selemon Barega of Ethiopia, Olympic 10,000m bronze medallist Jacob Kiplimo of Uganda, Olympic 5,000m silver medallist Mohammed Ahmed of Canada and two-time Olympic 5,000m medallist Paul Chelimo of the United States are the main contenders.

Friday night will also see Ethiopia’s 24-year-old Letesenbet Gidey aiming to lower the women’s 5000m world record of 14:06.62 that she set in Valencia in October 2020.

Gidey has since lowered the women’s 10,000m world record to 29min 01.03sec and the world half marathon record to 1hr 2min 52sec.

Elsewhere on Friday, the women’s two miles will see Sifan Hassan of the Netherlands, the Olympic 5,000 and 10,000m champion, facing Diamond League 5,000m champion Francine Niyonsaba of Burundi.

The latter, who was disqualified at the Tokyo 2020 Games, beat Kenya’s double Olympic 1500m champion Faith Kipyegon over 3,000m in Doha earlier this month.

The world best of 8:58.58, set by Ethiopia’s Meseret Defar in 2007, is sure to be under threat.

Saturday’s middle-distance action will be highlighted by the clash of Olympic 1500m champion Jakob Ingebrigtsen and world champion Timothy Cheruiyot, who renew their rivalry in the Bowerman Mile. 

Ingebrigtsen beat Cheruiyot for the first time in the Olympic final in Tokyo last year but the Kenyan beat his Norwegian rival a few weeks later to win over 1500m at the Diamond League final in Zurich.

Both men will need to be primed, however, to beat Kenya’s Abel Kipsang, who out-kicked Cheruiyot to win in Doha recently and who backed it up with 1500m victory in Birmingham last Sunday.

Kipyegon meanwhile will take on Britain’s Tokyo 2020 silver medallist Laura Muir and Gudaf Tsegay of Ethiopia in the women’s 1500m.

Hodgkinson faces an 800m field that includes home runner Ajee Wilson, who took the world indoor title earlier this year.

The men’s shot put will involve the respective Tokyo 2020 gold, silver and bronze medallists Ryan Crouser and Joe Kovacs of the United States and New Zealand’s Tom Walsh.
