Zapletalova, the New Queen of the Event

With Sydney McLaughlin-Levrone taking a break to welcome her first child, Emma Zapletalova has emerged as the revelation of the season. The Slovak athlete has claimed four Diamond League victories this year and lowered her personal best to 52.30 seconds. Her main challengers will be American Anna Cockrell, the world number two this season, and the experienced Jamaican Rushell Clayton. All the ingredients are in place for a thrilling race in an event that Swiss fans have come to love thanks to the achievements of Lea Sprunger.
