Tragedy struck during the Yellow River Stone Forest 100K race held on May 22, 2021 in Gansu, China. Sadly, 21 runners lost their lives during this 100-km trail running race. We would like to send our best wishes to the survivors, and our deepest condolences to the families and friends of the victims.

According to news reports, one of the main causes of death in this tragic event was hypothermia caused by extremely cold and wet weather that abruptly hit the race area.

Extremes of nature which may result in tragic deaths such as this can happen in any trail running race in any area and in any country. As race organizers, we have the responsibility to ensure the safety of all people in our race, and to correctly convey the risk of the elements to our participants.

The UTMF Race Committee is committed to keep improving the UTMF safety system, while exploring how we can cooperate with our participants in responding to risks, and to spread our knowledge and experience for the betterment and the promotion of the sport of trail running.

Last but not least, we would like to let you know that Mr. Liang Jing, who finished second in the UTMF2019, lost his life in this tragic event. This is a huge loss to the sport we love. We will always remember Liang Jing’s strong and wonderful performance in the UTMF2019. His energetic performance gave us the courage to give everything we have to take on difficult challenges. We would like to give thanks to his memory, and we pray from the bottom of our hearts that his soul may rest in peace.
