What risks did the silver marathon ignore?

Insufficient weather risk and safety guarantee.

1. Weather risk: The weather in Baiyin City is extremely bad and the temperature drops suddenly, which brings great challenges to the contestants and staff. The organizers did not fully predict and prepare for the weather on the day of the competition, resulting in insufficient protection and rescue for the contestants.

2. Insufficient security: The organizers did not provide enough security measures for the competition, such as emergency rescue and medical security. When the incident happened, the team members could not get effective rescue for a long time, which delayed the rescue opportunity.
