Twenty-one ultra-marathon runners have died after extreme weather conditions hit a 100-kilometer (62-mile) mountain race in northwest China, CNN says.
The high-altitude Huanghe Shilin Mountain Marathon began on Saturday morning in sunny conditions. But by 1 p.m. local time weather conditions had turned, with freezing rain, hail stones and gale winds lashing runners in Gansu County.
Liang Jing, one of China's well known ultra-marathon runners, was among those who died, a Hong Kong marathon group called Hong Kong 100 Ultra Marathon confirmed via a statement released on Sunday.
The marathon group said Liang had been a "favorite" member of the Hong Kong trail-racing community. He regularly participated in the annual Hong Kong 100-kilometer trail race, and was the runner-up in the last two years, it added.
It also described him as "one of the best ultra-endurance athletes in the world" and expressed condolences to his family.
As temperatures dropped in the Yellow River Stone Forest, runners started reported suffering from hypothermia, while others went missing.
The marathon organizers called off the race and launched a search party of 1,200 people to scour the complicated terrain. The search operation continued after dark.
