Race organisers accused of not heeding warnings after rain, hail, and gale-force winds forecast across Gansu province
Chinese authorities have launched an investigation into the death of 21 people in an ultramarathon over the weekend, as family and friends of the competitors who died in the freezing weather questioned how it was allowed to happen.
A further eight runners were injured when extreme weather hit the 100km (62 miles) high-altitude race in Yellow River Stone Forest near Baiyin in north-western Gansu province. More than 700 rescuers were sent in with thermal imaging drones and radar detectors to find the 172 competitors who were running with little protective clothing other than emergency foil blankets, some of which were reportedly shredded by high winds.
