Distance and timing basis

Ordered leg totals agree within rounding. Stop distances are approximate sums of rounded legs. Stops, delays, approach and any separate return travel add time. Basis: producer-declared routed record.

Reading history stays on this device. My road watch requires a separate selection; opening it does not subscribe this ride.

Distance and riding time are measured on the routed road. Check local closures and conditions before you ride.

Why this ride

356 km from Flims to Flims, about 5 h 38 of riding. It goes by way of Technikum, Sumpf, Hurden Rosshorn and Oterswil / Insel Eielen. The stored terrain estimate reaches about 1,850 m; a measured road-elevation profile is not available. A steady touring day rather than a sprint.

Waypoint introductions and full write-ups

  1. 1. Swiss Tectonic Arena Sardona

    Twice a year, in spring and autumn, the sun shines through a hole in a mountain ridge and lights up the church tower of Elm, a village in the Sernf valley of canton Glarus. The hole is the Martinsloch, a natural window in the Tschingelhörner, and it sits right on one of the most famous geological features in the world: a sharp line along the cliffs, clearly visible from the valley, where older rock lies on top of much younger rock. This is the Glarus thrust, and it helped geologists understand how mountains are built by the stacking of enormous slabs of the earth's crust. The Swiss Tectonic Arena Sardona was listed by UNESCO in 2008.

    Planning note

    Swiss Tectonic Arena Sardona is where the day begins. Next is Technikum.

  2. 2. Technikum

    Students at the technical university in Rapperswil study engineering on a lakeside campus, and beneath the shoreline in front of their buildings lie the remains of villages that people built on piles thousands of years ago. The site, named after the old Technikum, as the college was long known, is one of the prehistoric pile dwelling sites around Lake Zurich included in the UNESCO listing of 2011. Nothing is visible, but the idea that this shore has been home to people for so long gives a different perspective to a stroll along the promenade.

    Planning note

    Technikum comes up about 61 km into the recorded legs. Next is Sumpf.

  3. 3. Sumpf

    Zug-Sumpf was a Bronze Age village on the northern shore of Lake Zug, near the mouth of the river Lorze between Cham and Steinhausen, and the waterlogged ground preserved wooden floors, posts and objects for over three thousand years. Excavations in the twentieth century recovered pottery, bronze tools and even remains of food, and the site sits on the World Heritage list as part of the prehistoric pile dwellings around the Alps. Some of the finds are displayed in the museum of prehistory in Zug. Today the site lies under modern buildings and meadows, and only the name, which means swamp, recalls its watery origin.

    Planning note

    about 99 km into the recorded legs you reach Sumpf. Next is Hurden Rosshorn.

  4. 4. Hurden Rosshorn

    Where Lake Zurich narrows to a waist between Rapperswil and Hurden, a low peninsula runs out from the Schwyz shore, and at its tip, the Rosshorn, the remains of prehistoric lakeside villages lie beneath the shallow water. People lived here in the Neolithic and Bronze Ages, in houses built on wooden piles, and they also built some of the earliest known bridges across the narrows. The site is one of the prehistoric pile dwellings around the Alps that UNESCO listed in 2011, a group of sites that has given archaeologists a remarkably detailed view of everyday life thousands of years ago, preserved in the mud of lakes and moors.

    Planning note

    Hurden Rosshorn, about halfway. Next is Oterswil / Insel Eielen.

  5. 5. Oterswil / Insel Eielen

    Lake Zug is the quiet one among the central Swiss lakes, long and slender, with the Rigi rising steeply from its southern end and gentle farmland and orchards rolling down to its northern shores. Around its edges, as around many Alpine lakes, people built villages on the shore in prehistoric times, and the remains of these settlements at places like Oterswil and the little island of Eielen are among the sites of the transnational pile dwelling listing inscribed by UNESCO in 2011. Under water and mud, wooden piles, pottery and tools have survived for thousands of years.
