[1] Featuring the reigning Olympic, World, Commonwealth and European champions, who between them had dominated the global podiums since Tokyo in 2021, the women's 800 metres was one of the most hotly anticipated races of the championships.
2022 silver medalist Keely Hodgkinson, who gave Mu a scare in Eugene, came in as the world leader for 2023; her only defeat, a tactical masterclass from Commonwealth champion Mary Moraa at the Lausanne Diamond League.
After recovering her balance, Mu had to run around five athletes to get back to a qualifying second place behind 2022 bronze medalist Mary Moraa.
British number two Jemma Reekie, under a fresh coaching team, impressed in the semi-final to put herself forward as a wild-card medal chance in the final.
The race was acclaimed as one of the highlights of the championships, reinforcing the emerging and dramatic three-way rivalry between Moraa, Mu and Hodgkinson set to dominate the event for years to come, and acknowledging Reekie as one of the women most likely to bridge the gap to the Big Three.
