Sydney, Australia – August 31, 2025

Olympic champion Sifan Hassan has officially been confirmed for the TCS Sydney Marathon, set to take place on August 31, 2025. The Dutch superstar, known for her unprecedented range and fierce finishing kick, will bring global attention to one of the fastest-rising races on the international calendar.

But Hassan won’t have the spotlight to herself.

She will face a formidable challenge from Kenya’s Brigid Kosgei, the former marathon world record holder. Kosgei, who ran an astonishing 2:14:04 at the 2019 Chicago Marathon, is determined to reclaim her place at the top of women’s marathoning. With multiple major wins under her belt, including London and Chicago titles, Kosgei remains one of the most consistent and feared competitors in the sport.

This clash between two marathon titans promises to be one of the most compelling head-to-head matchups of the year. Hassan, who made a sensational marathon debut in 2023 and has since cemented herself as a serious contender at the distance, will look to further build her legacy. Meanwhile, Kosgei will aim to reassert her dominance and remind the world why she once redefined what was possible over 26.2 miles.

With the TCS Sydney Marathon bidding to become a World Marathon Major, this showdown adds star power and global significance to the 2025 edition.
