Dutch Sprinter Lieke Klaver, has set her sights ready for Oslo Diamond League that will take place on June 12, 2025, at the Bislett Stadium in Oslo, Norway.
Fresh from an emotionally charged appearance at the FBK Games in Hengelo, Lieke Klaver is now turning her focus to the highly competitive women’s 400m race.
The 2024 Olympic Champion in the 4 × 400 m mixed relay, known for her dynamic presence on the track and her growing international stature, is stepping into one of the deepest 400m fields assembled this season.
Klaver Overwhelmed
At the FBK Games, Klaver competed in the 200m and finished fourth in 23.40 seconds. This made her second-fastest Dutchwoman behind Minke Bisschops (23.14). The race was won by American sprinter Anavia Battle in 22.75 seconds.
Beyond the result, Klaver’s participation in Hengelo carried deep emotional significance. She wore a bib number that featured a quote from her brother. That was a personal tribute that resonated with many and underscored the sentimental weight of the occasion.

In a heartfelt Instagram post, Klaver expressed her appreciation for the meet. She referred fbk games “one of a kind” and giving a warm shoutout to @odidonederland. A supporter who likely helped bring the tribute to life. The moment, steeped in meaning, served as both a celebration of family and a source of motivation. Klaver now looks ahead to her key Diamond League appearances.
The 26-year-old is now set to race the 400 meters in Oslo. She will then continue to Stockholm and Paris. In Oslo, she’ll be part of a star-studded lineup featuring five of the eight finalists from the 2024 Olympic final. Also, seven of the top eleven on the current world rankings. It’s a stacked field where Klaver, with a personal best of 49.58 and a world ranking of No. 7, will have to be at her best.
A Star-Studded 400m Field in Oslo
Leading the charge is Poland’s Natalia Bukowiecka, the only woman in the field to have broken the 49-second barrier this season (48.90). The reigning European champion and Olympic bronze medallist arrives in Oslo as the woman to beat.

Rhasidat Adeleke of Ireland (PB 49.07), a 2024 Olympic finalist and European silver medallist. Amber Anning of Great Britain (PB 49.29), the 2025 World Indoor Champion, and Isabella Whittaker of the USA (PB 49.24), also add depth and danger to the roster.
Klaver’s main strength lies in her smooth running form, late-race resilience, and big-stage experience. A 2022 World Championships finalist (4th place) and 2024 European bronze medallist. She’ll be aiming to test herself against the world’s best and maybe, inch closer to that elusive sub-49.50 barrier.
Rounding out the field are young standouts. They include; Henriette Jæger (Norway), Lurdes Gloria Manuel (Czech Republic), and Barbados’ Sada Williams
