La Madrugada Tango Marathon, Festival and Cup runs 30 September–4 October 2026 in Istanbul. The long Tangocat title is a hint: this is not only a marathon floor. Festival and cup sit in the same week.
A dense tango week as September closes is a start-of-autumn marker for city dancers and short-haul visitors. Lineups and cup format can change on the source page.
