Overview
- Kai Pflaume staged the attempt live on Monday, November 2, as the season‑13 opener of Wer weiß denn sowas? and the show continued streaming until the run concluded.
- ARD scheduled a live double episode on Das Erste and moved to nonstop streaming in the ARD Mediathek so the broadcast could run until the record attempt was complete.
- The target was the marathon distance of 42.195 kilometres, to be covered on roughly a 30‑metre studio circuit requiring about 1,400 laps and supervised on site by a Guinness World Records representative.
- Pflaume is a seasoned endurance athlete who recently ran major city marathons and was supported on air by team captains Bernhard Hoëcker and Wotan Wilke Möhring during the live attempt.
- Medical experts warned the short, repeatedly curved loop causes asymmetric loading on knees, hips and tendons that raises injury risk, and producers’ safety choices for this event could shape how future studio stunts are planned.
