Overview
- Switzerland's Audrey Werro won the women's 800m in a meet record 1:55.33 after a blistering 54.64 opening lap set by pacemaker Myrte van der Schoot, but she could not sustain world‑record pace over the final 200 metres.
- Femke Broeders‑Bol finished a close second in a Dutch national record of 1:55.41, and Ethiopia's 18‑year‑old Saida Tsehaye took third in a personal best 1:56.92.
- Olympic champion Emmanuel Wanyonyi claimed the men's 800m in 1:42.19, powering past rivals over the final 20 metres for his first Diamond League 800m win of the season.
- Letsile Tebogo won the men's 200m in 19.87 and American Kayla White took the women's 200m in 22.18 with Britain's Amy Hunt second in 22.32, while Jamaica's Shericka Jackson pulled up with an apparent hamstring problem.
- The Lausanne meeting also produced meet records from Masai Russell and Rai Benjamin and serves as a tactical tune‑up for the remaining Diamond League stops and the World/Ultimate Championships in Budapest, with Werro now publicly cast as a potential challenger to the long‑standing 1:53.28 800m world record.
