The Inner Park Ring is a 52 km running loop that circles central Berlin, connecting many of the city’s parks, lakes, and green corridors.

The route starts and finishes at Tempelhofer Feld, the huge open space of the former Berlin Tempelhof Airport. From there it heads through the quiet garden neighborhood of Neu-Tempelhof and into Volkspark Wilmersdorf, a long green park that cuts through the city.

The Wai'anae Summit Trail (WST) follows the spine of the Wai'anae Range along the western side of O'ahu, creating one of the island's longest and demanding ridge traverses. The route runs roughly the length of the range, linking multiple summits and narrow ridgelines while staying almost entirely on the spine of the mountains. The route contains a combination of exposure and terrain variety across the entire traverse. Including long knife-edge ridges, steep choss climbs, and sections where ropes assist hikers over particularly steep or eroded terrain.
