In the summer of 2021, ultrarunner Karel Sabbe ran the Via Alpina trail in just 30 days. Averaging two marathons on a daily basis, he navigated the route 14 days faster than anybody else. As well as the Alps, Karel overcame sleep deprivation, illness and extreme weather. And he did it all with a camera crew in tow, documenting every step. This is the story of Karel’s Via Alpina FKT.
