According to the rescue headquarters, at about 1 pm on Saturday, hails, freezing rain and gales hit the area of the race's high-altitude stage between 20 to 31 km. Participants suffered from physical discomfort due to the sudden drop in air temperature. The race was halted when some runners went missing.

Local governments initiated an emergency response and gathered over 1,200 well-equipped rescuers to search for the missing persons, said Zhang Xuchen, mayor of Baiyin City, at the press briefing. The temperature dropped again during the night due to the area's complex terrain and topography, making the search and rescue more difficult, the report said.
