She is one of the main draws in the latest World Athletics Continental Tour Gold meeting, at which, last year, she threw 77.93 metres to restore her confidence and standing after two injury-ravaged years shortly before her second successful defence of the Olympic title.

Wlodarczyk has gone a whole year unbeaten since that restorative triumph in Bydgoszcz, with her most recent success coming at last month’s Kip Keino Classic in Nairobi, Kenya.

Her opponents include international teammate and Olympic bronze medallist Malwina Kopron, Finland’s Krista Tervo and New Zealand’s Lauren Bruce.

The men’s hammer throw brings together the top four from last year’s Tokyo 2020 Games and Poland’s gold medallist Wojciech Nowicki and bronze medallist and four-time world champion Pawel Fajdek will be ready to deliver to the satisfaction of home fans.

Their opposition includes Norway’s Eivind Henriksen and Ukraine’s Mykhaylo Kokhan, who finished second and fourth in Tokyo respectively, as well as Hungary’s world bronze medallist Bence Halász.

Olympic pole vault silver medallist Chris Nilsen of the United States will return to the arena where he set a meeting record of 5.92m last year that looks very likely to be raised given that he has already exceeded six metres both indoors and out this season.

The home challenge will be led by multiple world medallist Piotr Lisek and 2011 world champion Pawel Wojciechowski.

The men’s shot will be another almighty event given the presence of Brazil’s world indoor champion Darlan Romani, who is unbeaten this year but will be tested to the limits by two-time world champion Joe Kovacs of the United States and double Olympic bronze medallist and 2017 world champion Tom Walsh of New Zealand.

The men’s 100m field features African Games gold medallist Raymond Ekevwo of Nigeria, who has a 10.04sec clocking to his name so far this year.

In the women’s event, world and Olympic finalist Michelle-Lee Ahye of Trinidad and Tobago is hoping to repeat last year’s victory in the same arena.

In the women’s 100m hurdles, African record-holder Tobi Amusan of Nigeria and 2018 world under-20 champion Tia Jones of the US appear the pick of the field.

Meanwhile in the men’s 100m hurdles, multiple Polish champion Damian Czykier will take on South American champion Eduardo Rodrigues.

The women’s 400 metres - the event in which the late, great Irena Szewinska won Olympic gold in 1976 - sees the latest up-and-coming Polish one-lap runner, world under-20 silver medallist Kornelia Lesiewicz, facing Modesta Morauskaite of Lithuania, who clocked 50.49sec last week in Huelva.

Olympic finalist Viktoriya Tkachuk of Ukraine is favourite in the women’s 400m hurdles, having finished at last Saturday’s Prefontaine Classic Diamond League meeting in Eugene, California.

Olympic finalist Michal Rozmys and European indoor silver medallist Mateusz Borkowski carry home hopes in the men’s 1500m and 800m respectively.

Meanwhile in the women’s 800m, 2014 world indoor silver medallist Angelika Cichocka will be in focus.
