About This Race

The 50K strikes the perfect balance for runners seeking a substantial mountain challenge without the multi-day recovery demands of longer ultras. At 48 kilometers, this distance allows runners to experience Mount Yun's diverse terrain features while maintaining a pace that lets them truly absorb the mystical landscape and ancient cultural elements along the route. This option suits experienced trail runners ready to step into ultra territory or seasoned ultrarunners wanting to explore new terrain with intensity rather than pure endurance as the primary challenge.

Notable Features

The race takes place on Mount Yun, a location historically significant as a place once visited by Laozi, the founder of Taoism. Runners experience diverse terrain including pine forests, ice cave formations, and mountain peaks in what organizers describe as an emerald paradise of natural beauty combined with deep cultural heritage.
