The women's 800m has quickly evolved into one of the most captivating events in world athletics.
Eyebrows were raised when 400m hurdles star Femke Broeders-Bol made the decision to focus on two laps of the track and challenge Olympic champion Keely Hodgkinson for 800m supremacy, but very few forecast the emergence of Switzerland's Audrey Werro, who has dominated 2026 to win European gold and secure a maiden Diamond League trophy.
Werro defeated Hodgkinson in Stockholm in June with a 1.53.98, becoming only the third woman in history to go under the 1.54 mark, and the 22-year-old went even faster in the Paris Diamond League meeting, improving to a 1.53.80.
At the Diamond League meeting in Zurich last month, Werro ran a world-leading 1.53.70, raising belief that it's only a matter of time before the Fribourg-born athlete breaks Jarmila Kratochvílová's 43-year world record of 1.53.28.
But Werro is not the only individual who's been consistently improving. Broeders-Bol ran a 1.57.13 in Ostrava in mid-June, before improving to sub-1.56 by the end of the month in Paris. At the Diamond League meeting in Zurich, the Dutch ace ran a personal best 1.54.71 and in her latest outing, she pushed Werro all the way to the line in yet another indicator of her progress.
Hodgkinson's preparations for the inaugural Ultimate Championship have been hampered by a hamstring injury.
The Olympic champion has not been seen since finishing second to Werro at the European Athletics Championships in Birmingham after she opted to skip the Diamond League meeting in Zurich and the final in Brussels.
Hodgkinson will be hoping her prolonged absence means she's in the best possible condition to dethrone Werro and hold off the increasing threat of Broeders-Bol.
Further down in the market, world indoor bronze medallist Addison Miley will be looking to sneak onto the podium.
