The top three in Sunday's Beijing half marathon have been stripped of their medals, organisers said, following an investigation into the finish that saw China's He Jie controversially win.

"Today the 2024 Beijing Half Marathon Organising Committee issued a decision on the investigation and handling of the men's race results," a state media report said on Friday.

It added: "The trophies, medals and bonuses will be recovered."

The race's bizarre finish saw He cross the line first after two runners from Kenya and one from Ethiopia seemed to deliberately allow him to win.

All four were "punished" and their results cancelled, CCTV reported.

The Chinese Athletics Association said earlier this week they had met, issuing a statement vowing to make improvements to the sport in the country. (AFP)
