Beijing: Twenty-one runners have died after extreme weather struck a long-distance race in north-western China.
High winds and freezing rain hit participants in the 100km (60-mile) ultra-marathon in the Yellow River Stone Forest, a tourist site in Gansu province.
The race was halted when some of the 172 runners went missing, and a rescue operation was launched.
Many of the stranded runners reportedly suffered from hypothermia.
Officials said 151 runners were now confirmed safe, and that eight of them were injured.
Surviving participants said the forecast had shown some wind and rain was anticipated, but nothing as extreme as what they experienced.
About three hours after the start, a mountainous section of the race was hit by hail, heavy rain and gales, which caused temperatures to plummet, according to local officials from the nearby Baiyin city, the BBC news reported.
