I ran around Lake Tai from March 30 to April 6, 2025 unsupported.  Lake Tai is the third largest fresh water lake in China, flowing through the richest regions and civilizations for thousand of years.  Clockwise, there are Suzhou city, Huzhou city, Yixing city, Changzhou city and Wuxi city surrounding Lake Tai, covering two provinces JIangsu and Zhejiang.  Most people circle the lake via cars and bikes.  The total distance to walk/run around the lake is about 370 kilometres.
