Runmageddon in Warszawa, Poland. 2 events on Saturday, October 31, 2026.
Runmageddon Halloween is the costume edition, run in Warsaw on 31 October as a one-day, short-course event rather than a full race weekend. The obstacles are the standard Runmageddon set dressed for the occasion and the field runs in costume, so this is the least serious date on the calendar — closer to a themed mud run than a competitive OCR.
Two formulas run: Family over 2 km with 15 obstacles, open to adults running with children, and Formuła 5K over 5 km with 20 obstacles for everyone else. Neither is timed as a league round. It is an easy add-on if you are already in Warsaw for the Modlin race three weeks earlier.
The organizer has not published start times yet. Waves fill up.
