Overview
- The attempt began on Monday, November 2, 2026, and Pflaume completed a full marathon in the studio in 5 hours, 53 minutes and 21 seconds covering about 1,407 laps and earning official Guinness World Records certification.
- Producers converted the Hamburg studio into a roughly 30‑metre circular course, allowed short pauses to read questions, scheduled direction changes and provided a portable toilet while a Guinness representative monitored the attempt.
- The event lifted audience engagement with about 2.97 million viewers at the start, peaks above 3 million on linear TV, roughly 600,000 ARD‑Mediathek streams and more than 18,000 participants in the interactive app.
- Organisers cited Pflaume’s marathon experience, including recent city races, as context for feasibility, but sports scientists warned the tight, constant curves produce extra centripetal loading that stresses knees, hips and ankles and can cause cumulative microtrauma.
- ARD used the stunt to relaunch season 13 of Wer weiß denn sowas? and the certified result may encourage similar cross‑platform TV events while prompting closer scrutiny of safety and medical precautions for studio endurance challenges.
