The Macalline Red Star Xiamen meeting on 23 May has confirmed its men's 400m hurdles startlist this week, and it places the season's two defining names in the event — Karsten Warholm and Alison dos Santos — on the same Chinese track for a third time in three weeks. Warholm opened his Diamond League campaign at the Keqiao opener on 16 May; Xiamen, just seven days later, becomes the third meeting of the season and the second straight on Chinese soil. The startlist also confirms long jump world-record holder Mattia Furlani and Chinese sprinter Wu Zhiqiang in headline events.
The Warholm-Dos Santos rivalry remains the strongest single-event narrative in men's track and field. Warholm is the world record holder at the 400m hurdles in 45.94 from Tokyo 2020 and the only man in history to break 46 seconds; Dos Santos is the only other man to have run faster than 46.30, having stopped the clock at 46.29 in Eugene in 2022. Both ran the shorter 300m hurdles in Keqiao the previous week as part of a one-off Chinese-meeting innovation, but Xiamen returns to the standard 400m hurdles distance and is the first head-to-head over the full barrier sequence in 2026.
The supporting cast in Xiamen is built around Chinese national favourites and a strong field-events programme. Wu Zhiqiang, the home men's 100m sprinter, will run a Diamond League-discipline 200m on the night; Furlani opens his outdoor Diamond League season in the long jump at the same meeting, off the back of his 8.65m world record set in Rome a fortnight earlier. The women's Diamond League distance event is the 1500m, with a startlist that draws heavily from the Kenyan training base in Iten and from a small but well-credentialed Chinese contingent.
The meeting is the third of the 2026 Diamond League season — following Keqiao on 16 May and ahead of Rabat on 31 May — and the second to follow the rescheduling of the Doha opener to 19 June after the postponement triggered by the regional security situation in West Asia. The compressed early-season Chinese double-header has reshaped the way agents and athletes have planned the May block, with several leading sprinters and middle-distance runners now using Xiamen as their second-of-three pre-Rabat outings rather than a one-off.
For Warholm, Xiamen is also the last competitive race before his Bislett Games hurdles return on 11 June, with the Norwegian's coach Leif Olav Alnes flagging in a Friday interview that the Xiamen race is intended as a hard rehearsal for the Oslo home meeting rather than as a 2026 season-opener time trial. The men's 400m hurdles is scheduled for 19:35 local time on Saturday 23 May, with the full 14-event Diamond League programme broadcast live in Europe on the Wanda Diamond League digital feed and on selected national broadcasters. Tickets for the Xiamen meeting closed last weekend at full capacity.
