Zurich Diamond League: Two World Records and a High Jump Masterclass from Olyslagers
Two world records fell inside an hour at the Weltklasse Zurich Diamond League meeting on 27 August 2026, while Australia's Nicola Olyslagers reminded the sport that high jump rewards stubbornness as much as talent.
Brazil's Alison dos Santos broke the men's 400m hurdles world record, clocking 45.80 seconds to shave 0.14 off the previous mark of 45.94 set by Norway's Karsten Warholm (The Guardian). Soon after, Olympic champion Masai Russell set a world record of her own in the women's 100m hurdles, running 12.09 seconds to eclipse the old standard of 12.12 (ABC News). A night that belongs to the record books, yet Olyslagers carved out her own quiet corner of it.
The Australian won the women's high jump with a season's best of 2.02m, clearing every height on the night at the first attempt from her opening bar of 1.89m (Diamond League). She won by two centimetres from Ukraine's Iryna Gerashchenko. Olyslagers' lifetime best remains 2.04m — an Oceania record she set at the same Zurich street event last September, which also won her the 2025 Diamond Trophy before she went on to claim world gold.
What makes the victory notable is how she got there. Olyslagers had been experimenting with a new run-up and decided over the weekend that it simply was not working. She ditched it, returned to her familiar approach, and jumped herself to the top of the Zurich field (The Guardian). In a sport where one misjudged stride can end a competition, reverting to what you trust is its own kind of courage.
The 2026 season has tested her. She lost her Commonwealth title to teammate Eleanor Patterson earlier in the year. At Zurich, Patterson cleared 1.96m to finish fourth, while Ukraine's Olympic champion Yaroslava Mahuchikh — joint-sixth at the same height — could not mount a challenge on Olyslagers' lead.
The rest of the Zurich programme delivered its usual density of world-class marks. Pole vaulters Armand Duplantis and Emmanouil Karalis both attempted 6.32m — a height that would rewrite the event entirely. In the 3000m, American Parker Wolfe broke the meeting record with 7:27.43, edging compatriot Graham Blanks (7:27.92) and Australia's Cam Myers (7:27.97).
Switzerland's Audrey Werro produced the performance of the night for the home crowd. She won the women's 800m in a world-leading 1:53.70, becoming the first female Swiss athlete to win a Wanda Diamond League title. Jess Hull of Australia finished fifth in 1:58.24. In a non-Diamond League 200m race on the programme, Australian Torrie Lewis ran 22.66 for second behind Swiss winner Fabienne Hoenke (22.53).
Zurich's Letzigrund Stadium has long been the stage where seasons reach their crescendo. On this night, the crescendo belonged to two record-breakers and a high jumper who trusted her instincts over a new idea — and jumped 2.02m for her trouble.
