The Four Sisters Utral is an international Utral as a cultural landmark. The Foursiter Utral is an international event in the Sichuan area. A professional event registered by the China Athletics Association.Every year, we have a tradition to rush to Siguniang Mountain in November. Circumventing Siguniang Mountain in the ultra trail run is never just a competition. It’s an emotional attachment between some people and the mountains, a yearly-goal for some to improve themselves, a perseverance despite repeated failures, and a special bond shared among a group of people. It bears witness to our interwoven relationships of friendship, love, and kinship.
