World record holders return to track for Diamond League finale

World record holders Alison dos Santos and Masai Russell are set to compete at the Wanda Diamond League Final in Brussels on September 5, 2026, just days after breaking their respective world records in Zurich. Dos Santos set a new 400m hurdles world record of 45.80 in Zurich, improving on a mark he had previously threatened at the Tokyo Olympics where he won bronze. Russell also returns to competition following her record-breaking performance in Zurich, with both athletes headlining the second evening of action at the Allianz Memorial Van Damme.
