Survivors and bereaved seek answers after 21 deaths in China ultramarathon

Lack of cold-weather gear questioned as more harrowing accounts of survivors emerge

Loved ones and fellow competitors of 21 runners who died in extreme weather during an ultramarathon in north-western China are looking for accountability, as further accounts emerge of survivors' harrowing experiences.

Twenty-one runners died on Saturday when below-freezing temperatures, hail and high winds hit the race track: a 100km stretch of mountainous trail about 3,000 metres above sea level, in the Yellow River Stone Forest tourist site near Baiyin city. A further eight people were injured.
