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.

Admin note: The provided gpx file is one possible route.

The Shawangunk mountains (“Gunks”) are renowned for their beauty, accessibility, and opportunities for climbing and other outdoor recreation. There is one well-established ultra-distance FKT—the SRT (Shawangunk Ridge Trail). This FKT establishes another logical route, comprising the longest possible perimeter loop in the Gunks that doesn’t use any out-and-backs, bushwhacking, or public roads. In total, the route shows up as 51.2 miles on GPS (though is probably a few miles longer than that in actuality) and has about 8000’ of elevation gain.
