Route Introduction: The track sequentially traverses the three major scenic spots of Shuangqiaogou, Haizigou, and Changpinggou. From these valleys, you can enjoy the views of most peaks over 5000 meters in the Four Sisters Mountain area, as well as the south and north walls of Yaomei Peak.

The highest altitude is at the Tiaoshui Gou pass at 4560m. The overall race track is a mix of ice, snow, and rubble, presenting technical challenges with steep ascents and descents, and a very exposed environment. The difficulty of the 100-km race lies in long-distance running under complex high altitudes conditions, and in staying awake all night.
