mozart 100: Course, Elevation & Route Profile

Course & Elevation

The loop leaves Fuschl am See at five in the morning and hits its first serious climb before kilometre seven: 455 metres over 2.3 kilometres at around twenty per cent. From there the course drops to the Wolfgangsee, runs through Strobl and, at kilometre 26, starts the first big ascent of the day, the Schafberg, close to 800 metres over four kilometres followed by two short ramps steeper than 25 per cent up to the highest point of the route at roughly 1,700 metres.

The descent to St. Gilgen gives back a thousand metres in one go, and the hardest climb of the race follows immediately: the Zwölferhorn, 914 metres over 4.4 kilometres. Only past it does the route turn rolling, through Faistenau and Ebenau, until the Gaisberg asks for another 290 metres at kilometre 90. Over the Nockstein, Koppl and Hof, the loop finishes along the southern shore of the Fuschlsee.

On the ground it is a constant alternation of forest track, alpine pasture and open ridge high above two lakes, broken by village passages where the day's shorter races cross the route. As a UTMB World Series race the mozart 100 awards four Running Stones and Finals access, the time limit is 24 hours, and the finish area in Fuschl stays open until Sunday morning. The mandatory kit matches that: a hooded waterproof jacket, two headlamps or one with a spare battery, a survival blanket, a whistle and half a litre of water carried on the body. A running belt is not permitted at this distance, so it is a pack.

Pacing Strategy

The first 25 kilometres decide nothing and can cost everything. The climb at kilometre seven is steep enough to be attacked too hard in the dark, and the stretch to the Wolfgangsee that follows runs fast. Getting into a hike-and-run alternation that still feels like recovery is what opening the day well looks like. Plan to walk anything above fifteen per cent from the start, not from the point where there is no choice left.

The race is decided between kilometre 26 and 52, in the Schafberg and Zwölferhorn double. Some 1,700 metres of ascent and a thousand metres of steep descent sit within roughly 25 kilometres of each other, and the drop from the Schafberg to St. Gilgen is the section that sets the state of your quads for the rest of the day. Braking your way down costs more than it feels like: ten minutes won there are lost twice over in the closing 25 kilometres.

The real trap comes after that. Past the Zwölferhorn the profile looks harmless, but roughly 1,900 metres of climbing remain, including the Gaisberg at kilometre 90 with ten hours or more already in the legs. Build your fuelling so that you can still eat there, and expect the temperature to move through the day: a cool start, midday heat on the open ridges, and night by the time you finish.

Training plan for mozart 100: 12-week build

For most age-group runners the mozart 100 is a 16 to 22 hour effort, physiologically a continuous aerobic day with very long uphill blocks. Anaerobic spikes barely happen; what does happen is a load that is almost never flat, with only around eight per cent of the route level, over twenty per cent in the steep uphill band and a quarter in the steep downhill band.

That asks two things of your preparation that ordinary run training does not deliver. First, uphill endurance at hiking pace: structured climbs of 700 to 900 metres in one go, repeated inside a single long session, because the Schafberg and the Zwölferhorn demand exactly that twice in a row. Second, eccentric durability for the long descents. Extended downhill blocks on already fatigued legs are the most effective protection against the muscle damage that turns into lost time here from kilometre 60 onwards.

What decides the race is being able to hike uphill after eight hours and then still run downhill under control. Simulate it with back-to-back weekends of two long mountain days rather than one very long run, and schedule at least two headlamp sessions, because both the start and the finish can fall in darkness.

Conditions and kit are part of the training. In early June the Salzkammergut can be cold and wet at 1,700 metres while the valley is humid, and the mandatory equipment weighs several kilos. Train with the loaded pack you will actually race with, test your nutrition across full hours rather than single sessions, and deliberately try the waterproof jacket once in the rain.
