A host of Olympic champions will be involved at Hayward Field, which will host the postponed World Athletics Championships next year, including three of the five home individual gold medallists - women’s 800m winner Athing Mu, pole vaulter Katie Nageotte and shot putter Ryan Crouser.

On day one - the traditional “Distance Night in Eugene” - Hassan, who fell marginally short of a Tokyo treble earlier this month as she earned the 5,000 and 10,000m titles and took bronze in the 1500m, will attack the world 5000m record of 14min 06.62sec set by Ethiopia’s Letesenbet Gidey in Valencia last year.

Hassan set the European record of 14:22.12 in London two years ago.

In June this year, Gidey ran 29min 01.03sec to eclipse Hassan’s world 10,000m record of 29:06.82 set on the same Hengelo track just two days earlier.

Hassan’s response in Tokyo was impressive as she beat the Ethiopian to the Olympic 10,000m title with a final, unanswerable sprint around the final bend. Depriving her rival of one of her world records would mark another strong statement.

Gidey, meanwhile, will compete in the two-miles race that will also feature Kenya’s double world 5000m champion and Tokyo 2020 silver medallist Hellen Obiri and Burundi’s Rio 2016 800m silver medallist Francine Niyonsaba,

The meeting also offers home sprinter Sha’Carri Richardson, whose Tokyo 2020 opportunities were ended by a one-month ban after she tested positive for cannabis at the US Trials, the chance of matching her talents against the medallists.

Richardson, 21, stands third in this season’s world lists with 10.72sec and ran a wind-aided 10.64 at the trials.

She will be taking on Elaine Thompson-Herah, who retained her title in Tokyo in 10.61 - putting her second on the all-time list behind Richardson’s idol and compatriot Florence Joyner-Griffith, whose world record of 10.49 has stood since 1988.

Also in the field will be Tokyo silver medallist and 2008 and 2012 champion Shelly-Ann Fraser-Pryce, now 34, who has clocked 10.63 this year, and bronze medallist Shericka Jackson, who has run 10.76.

Richardson is also down to run the following event, the women’s 200 metres, where she will face world champion Dina Asher-Smith.

The Briton, who appeared in Tokyo after recovering from what she revealed had been a serious hamstring injury, pulled out of the 200m after narrowly failing to reach the 100m final, but returned to help her country earn bronze in the 4x100m relay.

Mu, 19, who wowed at the US trials before following through to win 800m gold in a national record of 1min 55.21sec, faces the two women who followed her home in Tokyo – Britain’s 19-year-old Keely Hodgkinson, who broke Kelly Holmes’s longstanding national record in clocking 1:55.88 – and fellow American Raevyn Rogers.

Britain’s fourth-placed Jemma Reekie is also in the field, as is Uganda’s 2019 world champion Halimah Nakaayi and another home runner, double world bronze medallist Ajee Wilson.

The men’s shot put will be among the field event highlights, with Crouser looking likely to produce another demonstration of his untouchable form having followed up his world record of 23.37 metres set at the US trials with an imperious retention of his Olympic title, setting an Olympic record of 23.30m and recording the five best throws of the competition.

Meanwhile the United States’ Olympic pole vault champion, Nageotte, will face Rio 2016 Olympic champion Katerina Stefanidi of Greece and Britain’s Tokyo bronze medallist Holly Bradshaw.

Norway's Jakob Ingebrigtsen, who set an Olympic record of 3min 28.32sec in beating Kenya’s world champion Cheruiyot to Tokyo gold – thus earning a first win over his rival at the 13^th attempt – will be seeking a second successive victory in the concluding Bowerman Mile.

In the women’s equivalent race, over 1500 metres, Kenya’s double Olympic champion Faith Kipyegon will headline a race including Britain’s Tokyo silver medallist Laura Muir, Canada’s fifth-placed Gabriela DeBues-Stafford and Australia’s sixth-placed Linden Hall.

While the world champion may not be in the women’s 3,000m steeplechase field, the Olympic champion – Uganda’s Peruth Chemutai – will be, as will home runner Courtney Frerichs, the Tokyo silver medallist.

Saturday’s programme also contains a mouth-watering men’s 100 metres event involving four of the Tokyo finalists, including US sprinter Fred Kerley, the home silver medallist.

Kerley, the 2019 world 400m bronze medallist with a best time of 43.64, has concentrated to good effect on the shorter sprint this season and will be favourite in a field that also contains Canada’s 100m bronze medallist and 200m Olympic gold medallist Andre De Grasse, along with two other Tokyo finalists, fourth-placed Akani Simbine of South Africa and American Ronnie Baker, who was fifth.

The men’s 800m will feature the Tokyo gold and silver medallists, Kenya’s Emmanuel Korir and Ferguson Rotich, as well as home finalist Clayton Murphy and Britain’s Elliot Giles.

Tokyo gold and bronze medallists will be in evidence in the men’s triple jump, where Portugal’s champion Pedro Pablo Pichardo and Hugues Fabrice Zango will be in the field along with home jumper Will Claye, who was fourth.

The men’s 200m will include home sprinters Noah Lyles and Kenny Bednarek, the respective Olympic silver and bronze medallists, along with the Olympic 400m hurdles silver medallist Rai Benjamin.

In the women’s 400 metres hurdles, another United States Tokyo silver medallist, world champion Dalilah Muhammad, will return to action having lost a monumental struggle with compatriot Sydney McLaughlin in Tokyo that saw both runners finish inside the previous world record.

The stellar cast list goes on in the men’s two miles, which will feature Ethiopia’s Olympic 10,000m champion Selemon Barega, Paul Chelimo of the United States, the Olympic 5,000m bronze medallist, and Uganda’s Olympic 10,000m bronze medallist Jacob Kiplimo.
