Nine reigning Wanda Diamond League champions are in action at the World Athletics Indoor Championships in Poland this weekend, as they continue their journey towards the beginning of the outdoor season.

Mondo Duplantis, Julien Alfred and Nicola Olyslagers are among those hoping to add another global title to their mantlepiece in Kujawy-Pomorze, just six months after claiming the Diamond Trophy in Zurich last September. Meanwhile, the 2026 Diamond League season continues to take shape, with a flurry of meetings adding world record breakers to their entry lists this week.

Australia's 2000m world record holder Jessica Hull joined an already star-studded Xiamen line-up on Monday. The 29-year-old will headline the women's 1500m at the Red Star Macalline Xiamen Meeting on May 23, for which tickets are now on sale

On Wednesday, Xiamen also revealed a world-class men's 100m field which includes Olympic 200m champion Letsile Tebogo, Olympic silver medallist Kishane Thompson, reigning Diamond League champion Christian Coleman, former Diamond League champions Trayvon Bromell and Kenny Bednarek and South African superstars Akani Simbine and Gift Leotlela. 400m world record holder Karsten Warholm is set to make an emotional return to London in July, nine years after he won his first world title there in 2017. 

Stockholm announced two world record holders this week, with Mondo Duplantis returning to action in the pole vault and Keely Hodgkinson set to race the 800m. Elsewhere, Olympic and world champion Tara Davis-Woodhall will be looking to defend her Prefontaine Classic long jump title in Eugene on July 4.
