Overview
- Kai Pflaume completed the full marathon distance while moderating Wer weiß denn sowas, finishing the certified attempt in 5 hours, 53 minutes and 21 seconds, according to ARD.
- The run took place on a roughly 30‑metre studio circuit in Hamburg and required about 1,407 laps to reach 42.195 kilometres.
- A representative from Guinness World Records monitored and formally certified the attempt, and the broadcast allowed short pauses and continued live streaming in the ARD‑Mediathek until the goal was reached.
- Sports scientists warned that repeated tight turns on a short loop create asymmetric joint stress and raise the risk of microtrauma to knees, hips and tendons despite planned direction changes and pauses.
- The event drove strong audience numbers on linear TV and in the Mediathek, boosting the season launch for the show and spotlighting how live stunts can combine promotion with new safety questions; Pflaume’s own marathon experience helped make the attempt feasible.
