In the Middle Ages the Rennsteig marked the boundary of the Duchy of Franconia with the Landgraviate of Thuringia. Even today it forms a clear border between the Franconian part of South Thuringia from the otherwise overwhelmingly Thuringian-Upper Saxon state of Thuringia. The Rennsteig is the language border separating the East Franconian dialects of Hennebergisch, Itzgründisch and Upper Franconian from the Thuringian dialects of Central Thuringian, Ilm Thuringian and Southeastern Thuringian, which is spoken in the mountains, in northern parts and east of the Thuringian Forest. The Rennsteig is also the watershed between the river systems of the Werra/Weser, Saale/Elbe and Main/Rhine. The catchment areas of all three river systems meet at the Dreistromstein (Three Rivers Stone) near Siegmundsburg.
Today the Rennsteig is designated by the German Mountain and Hiking Club (Verband Deutscher Gebirgs- und Wandervereine) as an outstanding high-grade hiking trail. It was discovered by August Trinius for the hiking fraternity and became famous well beyond the borders of Thuringia and Franconia mainly through the publications of the Rennsteig Club founded in 1896. The Rennsteig Cycle Way was opened on 19 June 2000. Most of it is provided with a water-bound surface, some sections also run along quiet country lanes. Here and there it departs from the course of the historic Rennsteig, so that steep inclines may be avoided. It is therefore about 30 km longer than the hiking trail.
The Rennsteig is connected to the E3 European long distance path, which goes from the Atlantic coast of Spain to the Black Sea coast of Bulgaria, and the E6 European long distance path, running from Arctic Finland to Turkey.
The Rennsteig runs along the ridge of the Thuringian Central Uplands from northwest to southeast mostly at heights of around 500 to 970 metres. It begins in the Eisenach town quarter of Hörschel by the River Werra (196 m above NHN) and ends after 169.3 km in Blankenstein by the River Saale (414 m above NHN). In 2003 the Rennsteig was re-surveyed by the Thuringian State Office for Survey and Geoinformation; they reported that it had a total length of 169.29 km. The marking along the trail is very good, usually indicated by a white R. Along the Rennsteig there are small, open shelters about every 5 to 10 kilometres.
The course of the Spitter stream, the only river in the central section of the Rennsteig, crosses the trail in the Ebertswiese nature reserve, at a height of 700 metres, before feeding the nearby Spitter Waterfall. Another stream that crosses the trail is the Dober in the southeastern part of the route, which forms part of the Franconian Forest immediately by the Thuringian-Bavarian border west of Brennersgrün, part of the borough of Lehesten.
Three tunnels run under the Rennsteig: One is the eponymous Rennsteig Tunnel, which is in fact two tunnels that are 7916 and 7878 metres long, making it the longest road tunnel in Germany. The tunnel was opened in 2003 as a motorway tunnel for the A 71 autobahn. The second is the 3039 metre long Brandleite Tunnel, which was opened in 1884 and leads the Erfurt-Schweinfurt railway under the Thuringian Forest. Both tunnels only have a vertical height difference of seven metres between each end. The third is the 549 metre long Förtha Tunnel on the Werra Railway.
A German mountain path is she! It flees the towns and hides its bashful course amongst the thickets.
— Am Anfang by Joseph Victor von Scheffel, 1863
Around June time, when from the gorges of the wooded heights, which run through the Thuringian Basin, the heavy scent of jasmine wafted down from the alder buckthorn, those were delightful walking days, here through the balmy fertile land almost free of industry with its friendly clustered villages of timber framed houses; and then onward out of the tapestry of arable fields, dominated by cattle-breeding farms, and followed the legendary highland path onto the mountain ridge with its spruce and beech - the Rennsteig - which, with its downward sweeping views into the Werra valley, ran from the Franconian Forest to Eisenach, the Hörselstadt, and became more and more beautiful, meaningful, romantic…
First record and meaning of the name 
The Rennsteig was first mentioned in 1330 as the Rynnestig. Etymologists are inconclusive about the origin of its name. It may go back to Rain, hunter's jargon for "border". In Old High German, a renniweg is a narrow footpath or bridleway in contrast to a Heerstraße or military road. In records dating back to 1546 the path is referred to as the Rensteig.
In addition to the well-known Rennsteig trail itself, there are about 250 other "Rennsteigs" and "Rennwegs" in German-speaking countries. Some of these are older and some more recent that that of the Thuringian Forest. This casts doubt upon its meaning as a genuine boundary path.
Rennsteig stones 
Along the Rennsteig there are about 1,300 historic boundary stones. Since the 16th century the Rennsteig, most of which was a border path, was marked with these political and national emblems. Of particular note are the 13 so-called Dreiherrensteine, of which only ten lie immediately on the Rennsteig. In local parlance these stones became known as Rennsteigstein or Rennsteig stones. The boundary stones surviving today stem mainly from the 18th century. In addition to boundary stones, there are also forest stones, stone crosses and monuments along the trail.
In Oberhof during the GDR period, there was a hotel (later demolished) of the same name in the shape of a boundary stone.

Rennsteig Run 
Since 1973 the GutsMuths Rennsteig Run, an organised ultramarathon, has taken place on the Rennsteig. With more than 14,000 participating runners and walkers it is one of the largest events of its type in Europe.
The Rennsteiglied is a folk song, that symbolises the spirit of the Thuringian people. Its was written by Karl Müller, the music is by Herbert Roth.
