The MT. Siguniang Ultra Tour is an international event held at a renowned landmark in Sichuan Province, officially registered by the China Athletics Association. Each year, we carry on a tradition of converging on Siguniang Mountain in November. Circumventing Siguniang Mountain in the ultra trail run is more than just a competition; it’s a deep emotional connection between participants and the mountains, a yearly milestone for self-improvement, and a testament to perseverance through repeated challenges. It fosters a unique bond among all involved, witnessing the intertwining relationships of friendship, love, and kinship.
