all day



Long course

Over 38.1 kilometres, runners will battle a change in elevation of 2,908 metres. Starting in Sedrun, at the Porta Alpina high above the Gotthard Tunnel, the course follows narrow paths to Lake Toma, the source of the Rhine – and no less spectacularly, returning over Piz Pazzola through the high-alpine landscape of the Surselva. An unforgettable course that runners will find addictive.

Short course

A shorter trail is available as well. It also provides a full panorama over 16.2 kilometres, featuring a change in elevation of 1,225 metres up the back of the Tgom with its unforgettable views.
