Ultra-marathon running: How safe is the sport?
The 2021 Yellow River Stone Forest 100km trail race in Gansu province, China, ended in tragedy in May, when unexpectedly severe weather resulted in the deaths of 21 of the 172 competitors. Among them was the Chinese champion Liang Jing, who in 2018 won the Ultra Gobi—three and a half days of non-stop running across 400km of the Gobi desert.
