Gravel po lodzku - dogrywka is a gravel cycling event in the Lodz area of central Poland, held in late September. Its base is the Center of Culture and Ecology in Plichtow, where riders find the event office, toilets, start line, and finish line. The format is an individual, muscle-powered bike ride on a GPX-marked route, without outside support.
The listed 160k course is about 150 km long, flat on paper, with 0 m of elevation gain and a 0% average gradient. It is classified as GDX3 and counts toward the GDX Gravel Ranking. Entries are capped at 150 riders, making it a compact gravel day rather than a large mass event. The rules emphasize self-sufficiency, meaning riders need to manage navigation, food, repairs, and pacing.
