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.
259 km from Reinach to Reinach, about 4 h 15 of riding. It goes by way of Hurden Seefeld, Swiss Tectonic Arena Sardona and back through Hurden Seefeld. The stored terrain estimate reaches about 1,850 m; a measured road-elevation profile is not available. The line favours views over speed.

1. Prehistoric Pile Dwellings around the Alps
Five thousand years ago, people were building houses on stilts at the edge of lakes across the Alps, and then the lakes rose, buried the houses and kept them almost perfectly in the mud. The remains of these pile dwellings, found in the nineteenth century when a drought lowered the water, include posts, tools, textiles, food and even bread, and they gave archaeologists an extraordinary view of Stone Age and Bronze Age life. A hundred and eleven of the sites, in six countries, were listed by UNESCO in 2011, and the Swiss share is the largest.

Planning note
Prehistoric Pile Dwellings around the Alps is where the day begins. Next is Hurden Seefeld.
2. Hurden Seefeld
Lake Zurich has a narrow waist, and at the waist stands a long causeway called the Seedamm. It links Rapperswil on the north shore with the Pfaffikon side on the south, and the peninsula of Hurden sits at its northern end. The upper lake, the Obersee, lies to the east, a quieter, shallower basin with reed beds, while the main lake stretches away to the west. Behind it all, the Glarus Alps and the Churfirsten rise to the horizon on a clear day.

Planning note
Hurden Seefeld comes up about 67 km into the recorded legs. Next is Swiss Tectonic Arena Sardona.
3. 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.
