Course & challenge

100 Miles

The start time is the point of the race. Leaving at six in the evening puts the first big climb, to the Wildseeloder above Fieberbrunn, into what the organiser calls the golden hour. The night is spent on the ridges of the Kitzbühel Alps, with the lit Jakobskreuz as the landmark in the dark, and the morning arrives on the Kitzbüheler Horn. The course is a loop: panoramic ridgelines, rocky passages and grassy mountains, back to the finish in Fieberbrunn.

Forty-five hours from a Thursday evening start means the last finishers come in on Saturday afternoon, around 15:00, and most of the field spends at least one full night outside. The organiser publishes an aid station plan with the food and drink at each stop, but no intermediate cutoffs on the race page, so the 45-hour limit is the number to plan around. It is a race for runners who already know what a night on a mountain feels like.

This page belongs to the 2027 edition of the 100 Miles. For the people waiting in Fieberbrunn the long stretches between valleys are the hard part. On Livebib the runner shares a link to their own broadcast: their position on the course line, distance covered and a finish estimate that moves with the pace. When the phone drops signal on a ridge at three in the morning, the dot carries on along the course and is marked as estimated instead of freezing. No app, no account, and the runner chooses who gets the link.
