Canadian hammer thrower Ethan Katzberg broke two records on the way to his second consecutive world title win on Tuesday at Tokyo’s National Stadium.
The 23-year-old from Nanaimo, B.C., had his second throw travel 84.70 metres, breaking both the championship record (83.63) as well as his own previous Canadian record (84.38).
The championship record had stood for 18 years before Katzberg unleashed the best throw of the 2025 season. His winning mark was 1.93m longer than his closest competitor.
Germany’s Merlin Hummel (82.77) won the silver medal while Hungary’s Bence Halasz (82.69) took bronze.
Katzberg’s win completes yet another Canadian sweep of hammer throw gold after compatriot Camryn Rogers won her event on Monday. The Canadian duo have both won back-to-back world titles and were both crowned Olympic champions at Paris 2024.
Canada now has three medals at this year’s world championship, the hammer throw golden sweep plus men’s race walker Evan Dunfee gold-medal win on Sunday.
