Authorities crack down on sports including trail running and wingsuit flying ahead of centenary celebrations
China has indefinitely suspended extreme sports events, including ultramarathons, trail running and wingsuit flying, in response to the deaths of 21 long-distance runners in Gansu last month.
Extreme weather hit Yellow River Stone Forest trail race in Gansu province a few hours into the race on 22 May as many of the competitors were crossing a remote and treacherous part of the 100km mountain track. Of the 172 competitors, 21 died and eight were injured. Scores of competitors sheltered in caves, some rescued by residents from nearby villages.
