The Wanda Diamond League meeting in Silesia will feature high-profile matchups, including Julien Alfred competing against Melissa Jefferson-Wooden in the women's 100m, Karsten Warholm facing Alison dos Santos in the 400m hurdles, and Nicola Olyslagers taking on Yaroslava Mahuchikh in the high jump.
Several world record holders are participating, such as Mondo Duplantis, Ja'Kobe Tharp, and Jakob Ingebrigtsen, who returns to Diamond League competition for the first time in nearly two years.

Jefferson-Wooden won last year's Silesia race, equaling the meeting record of 10.66 seconds. The field also features Sha'Carri Richardson, Shericka Jackson, Tina Clayton, Tia Clayton, and local athlete Ewa Swoboda.
The men's 100m includes world champion Oblique Seville, seeking his second Diamond League win of the season, against Kayinsola Ajayi, Emmanuel Eseme, Akani Simbine, Jordan Anthony, and Kenny Bednarek. Preliminary heats will precede the final.
In the 400m hurdles, world record holder Karsten Warholm races against Brazil's 2022 world champion Alison dos Santos. Dos Santos holds the season's world-leading time and has beaten Warholm three times this year, while Warholm claimed a victory over him in London. The flat 400m will feature Olympic and world hurdles champion Rai Benjamin against Collen Kebinatshipi, who has set Diamond League records in Paris and Monaco.
In the women's 400m, undefeated Olympic champion Marileidy Paulino will compete against local athlete Natalia Bukowiecka. Paulino has won several Diamond League meetings this year, including a meet record and personal best of 48.48 seconds in Paris.
