The village of Fuschl am See goes to bed at a reasonable hour. Restaurants close by ten. The lake reflects the last of the western light through a stand of larch above the shore. Tomorrow at 05:00, roughly 500 trail runners will cross the starting mat in the dark and begin one of central Europe's most compelling mountain ultras, and the village will wake to find them gone.
This is the rhythm of race eve at the mozart 100 by UTMB. Quiet, then eruption, then the long wait for runners to come home.
The Course: Two Mountains, One Lake Region
The mozart 100 — 119 kilometres, 5,700 metres of elevation gain — is built around the geography of the Salzkammergut, the Austrian lake district that inspired The Sound of Music and holds a staggering concentration of alpine terrain within an hour of Salzburg.
The race begins at Fuschl am See (559m elevation) in the dark, moving first along the southern shore of the Fuschlsee and then climbing into the forest above the lake. The first major landmark is St. Gilgen — the village on Lake Wolfgang's western shore, a postcard of painted facades and a church Mozart's mother was allegedly baptised in. By the time the race's front runners arrive here in the early light, they'll have climbed through 800 metres of gain and will be looking at the day's first summit.
The Schafberg is Stage One of the course's two defining challenges. The mountain rises to 1,783 metres above the southern shore of the Wolfgangsee. Its summit is served by a steam cog railway in summer — a tourist attraction that the mountain has not managed to prevent becoming simultaneously one of Austria's most enjoyable and most demanding trail-running objectives. The race ascent takes the direct trails, cutting up through the forest band and out onto the exposed rocky upper slopes. At the top, on a clear morning, you can see the chain of Salzkammergut lakes stretching south toward the Dachstein massif.
The Zwölferhorn (1,522m) arrives later, after the course descends into the valley and makes its way through the central Salzkammergut. The summit station sits above St. Gilgen and is accessible by cable car for non-runners — for the field of the mozart 100, it is accessible by whatever the legs have left at kilometre 85 or so. The Zwölferhorn's descent is technical: loose rock on exposed ridgelines before the trail drops back into the lakeside forest.
Between these two summits, the course threads through the Salzkammergut's forest paths, lakeside tracks, and alpine meadows. The lower sections are runnable — genuinely runnable, with firm footing and wide paths. The upper sections above tree line are technical in both directions. The combination is what makes this event a true mountain ultra rather than an alpine hike with a timing chip.
The Field
The sold-out field includes multiple UTMB-qualified elites drawn by the race's positioning in the World Series as a qualifier for Chamonix. Austrian trail running has a strong domestic contingent here — the local knowledge advantage is real when the course uses unmarked ridgeline sections above Schafberg. The international field spans European mountain running, with several athletes using this as a late-May fitness gauge before the Western States and Hardrock windows.
In the women's race, watch for athletes from the UTMB mountain running scene who prefer a high-gain point-to-point style over flat ultras. The Salzkammergut rewards technical mountain runners over flat-road speed.
In the men's race, the Schafberg's direct ascent will sort the climbers from the endurance athletes within the first 25 kilometres. Whoever comes off that summit in the lead will have the confidence of an early advantage and 90 kilometres of alpine terrain ahead to defend it.

The athlete briefing ran this afternoon in Fuschl's community hall. Standard UTMB World Series briefing content: mandatory gear checks, course changes flagged (a section east of the Zwölferhorn adjusted for trail maintenance), checkpoint cutoff times reviewed. Weather outlook: partly cloudy, temperatures between 4°C at Schafberg summit and 14°C at the lake. Wind possible on exposed ridges above 1,400m. Rain not forecast until Saturday afternoon — well after the expected winning time.
The start will run from Fuschl's lakeside square at 05:00. Headlamps required through the first 90 minutes. The first checkpoint (Strobl, km 35) sees the front runners in approximately 3.5 to 4 hours. The winning time — based on recent editions — lands somewhere between 13 and 15 hours, with the women's leader typically 14 to 17 hours.
Why This Race Belongs in the Calendar
The mozart 100 is not a race that manufactures a setting. The Salzkammergut's landscapes are not enhanced for the event — the lakes, the mountains, the medieval villages are simply there, and the race passes through them. Running the southern shore of the Wolfgangsee in the early morning with Schafberg's summit lit above you is an experience that requires no improvement.
The race is also a genuine mountain test in a part of the world that gets less attention than the Western Alps — Austria's alpine running tradition runs deep, with Salzkammergut ultras embedded in the European circuit for a decade. The UTMB World Series designation has brought international visibility to a race that deserved it.
Come dawn tomorrow, the field will be 30 kilometres in and the Schafberg will be getting close. Tonight, Fuschl sleeps.
