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.
From Innere Stadt it runs 313 km to Innere Stadt; allow about 4 h 32 of riding. The stops in between: Frontiers of the Roman Empire - The Danube, Carnuntum - Legionslager, Zwentendorf - Kastell and Traismauer - Kastell Römertor. A steady touring day rather than a sprint.
Waypoint introductions and full write-ups
1. Vienna
Vienna rewards the rider who parks the bike and walks. The Innere Stadt, the old centre, sits inside the line of the Ringstrasse, the great boulevard laid out in the nineteenth century where the medieval walls once stood, and it is lined with the opera house, the parliament, the university and a procession of grand museums. At the heart is Stephansdom, the cathedral with a roof of coloured tiles and a tall south tower that has been a landmark for centuries. The Hofburg, once the imperial palace, takes up a sizable chunk of the neighbourhood.

Planning note
Vienna is where the day begins. Next is Frontiers of the Roman Empire - The Danube.
2. Frontiers of the Roman Empire - The Danube
Marcus Aurelius, emperor and philosopher, spent several years at Carnuntum during his wars against the Germanic tribes north of the Danube, and he is thought to have written part of his Meditations here; the third book carries the note that it was written at Carnuntum. In the second century, this was one of the most important places on the Roman frontier: a legionary fortress, an auxiliary fort and a civil town that grew into the capital of the province of Upper Pannonia, with tens of thousands of inhabitants. Today, the archaeological park at Petronell-Carnuntum and Bad Deutsch-Altenburg shows reconstructed houses, a bath and streets built using Roman methods, two amphitheatres, and the Heidentor, a great ruined triumphal arch standing alone in the fields. The Danube Limes became a World Heritage site in 2021.

Planning note
Frontiers of the Roman Empire - The Danube comes up about 43 km into the recorded legs. Next is Carnuntum - Legionslager.
3. Carnuntum - Legionslager
Carnuntum was a Roman city, a legionary base and, for a time, a capital. The Fourteenth Legion, the Gemina, was stationed here from the first century, and the camp, with its great barracks and parade ground, guarded a crossing of the Danube where the Amber Road from the Baltic met the river. By the second century it was the capital of the province of Upper Pannonia, with an amphitheatre, baths and a population of tens of thousands. The emperor Marcus Aurelius is said to have spent part of the German wars here, and tradition holds that he wrote some of his Meditations in the camp.

Planning note
about 44 km into the recorded legs you reach Carnuntum - Legionslager. Next is Zwentendorf - Kastell.
4. Zwentendorf - Kastell
The Danube flows broad and brown past Zwentendorf, a quiet village on the Tullnerfeld plain west of Vienna, and for once the most famous building in the area is not the oldest one. Zwentendorf is where Austria built a nuclear power station in the 1970s and then, after a national referendum in 1978, decided never to switch it on. The plant still stands by the river, complete and unused, now a training site and a curiosity.

Planning note
Zwentendorf - Kastell, about halfway. Next is Traismauer - Kastell Römertor.
5. Traismauer - Kastell Römertor
A Roman gate still stands in Traismauer, a small town on the Traisen just before the river reaches the Danube, and cars and bicycles pass through it every day. The Römertor, as it is called, is one of the best preserved Roman gates in Austria, part of the fort of Augustianis, which guarded the Danube frontier, the Limes, here. The fort was modified and reused in later centuries, and towers and walls survive in the town's fabric. Since 2021, the Danube Limes has been a piece of the World Heritage property for the frontiers of the Roman Empire.

Planning note
The route ends here after 313 km.
