What this video covers

Thilo, co-owner of the sailing channel Blue Horizon, describes a six-year physical and mental decline during a liveaboard sailing life and how he reversed it by running a solo marathon on Formentera in 2025. After years of daily alcohol and cannabis use, minimal exercise, and heavy social-media consumption in the Caribbean, he stopped at 6 km during an 18 km run with friends in Germany — a failure that prompted him to sign up for the Cologne Marathon with those same friends.8:42 Unable to fly back from the boat for the race, he instead ran a self-organized 42 km route on Formentera two days before the Cologne event: a point-to-point course to the island's lighthouse and back, roughly 21 km each way, with significant heat and steep climbing.13:39 Leonie supported him by bike, carrying water and supplies.16:50 Thilo finished in under four hours at a 5:20–5:30 min/km pace for the first 35 km before the final stretch broke him, running at 93 kg over 1.80 m. He identifies the combination of daily substance use, social-media scrolling, and lost athletic routine as compounding causes of low mood and poor discipline, and argues that rebuilding a running habit — every second or third day — restored both fitness and mental state.27:54
