Five historic facts

• 10 of the 11 fastest times in championship history (in all conditions) in the 100m hurdles have been set in either the 2022 or 2023 editions of the World Championships
• In the 42-year history of the World Championships, only Americans Gail Devers (1993-95) and Michelle Perry (2005-07) have successfully defended their 100m hurdles titles
• The last seven global 100m hurdles finals have produced seven different champions. The last repeat champion was Danielle Williams (JAM) who won world titles in 2015 and 2023
• Sally Pearson's (AUS) winning time of 12.28 is the fastest wind legal winning time in championship history. She is one of the ambassadors for the 2025 World Championships
• The championship record stands to Tobi Amusan (NGR) with 12.12, also the world record, from the semifinals of the 2022 World Championships. Her winning time of 12.06 was wind-assisted at +2.5 m/s

Potential storylines

• Four of the eight fastest 100m hurdlers in history are on the entry-list: 1. Tobi Amusan (NGR) 12.12, 2. Masai Russell (USA) 12.17, =5. Grace Stark (USA) 12.21, =7 Ackera Nugent (JAM) 12.24 
• Can Danielle Williams (JAM) become just the second three-time winner of the 100m hurdles title after Gail Devers between 1993-99?
• Can Masai Russell become the first athlete since Sally Pearson in 2011-12 to win world and Olympic titles in back-to-back years? At the pre-event press conference, she said: “When my back is against the wall and competition is high, I just turn into something else – when the pressure is on. I always tell myself: ‘Pressure makes diamonds.’ And I never wanted to be an individual that can make it to the final or run fast times but never put it together."
• Will we see the second sub-12.2 winning time (and first wind legal) in World Championships history? Masai Russell: “I think sub-12 is definitely possible. We’ve seen the times drop over and over every year. 12.20 is starting to become the new norm, which is crazy.”
• Could there be a European medallist for the first time since 2017? Nadine Visser (NED) and Ditaji Kambundji (SUI) are in contention to win their country’s first ever medals in the 100m hurdles in World Championships history.
