The Sonnenwendlauf Markkleeberg Winter-Edition is a road race around Cospudener See in Markkleeberg, on the southern edge of Leipzig. It is part of the Sparkassen-Sonnenwendlauf series and is timed for the winter solstice, with runners participating on the shortest day of the year.
The route is a lap around the lake, starting from the event area at Ostuferweg near the Cospudener Combüse. After the run, participants gather by a solstice fire with music, grilled food, and drinks. All entry fees support a good cause, making the event a local running occasion and a midwinter fundraiser.
