The Rennsteiglauf (full name GutsMuths-Rennsteiglauf) is a trail running event on the Rennsteig path in the Thuringian Forest.
The four participants Hans-Georg Kremer, Hans-Joachim Römhild, Jens Wötzel and Wolf-Dieter Wolfram ran without any competitive intention and reached the finish together after 9:55 hours.
Eight of twelve participants reached the finish line after 10:35 hours: G. Clausnitzer, K. Gottert, R. Knoch, H.-G. Kremer, H.-J.
The run was organized on a voluntary basis and initially remained without support from the DTSB board.
Trademarks are the stomach-friendly gruel at the aid stations, the dedicated helpers along the course who are recruited from local sports clubs, and the "dumpling parties" on the eve in the starting towns as well as the runners' parties in the finishing town of Schmiedefeld am Rennsteig.
