St. Gilgen → Fuschl Am See
Race guide
Updated 19 July 2026
The mozart Ultra is the 84 km centrepiece distance of the mozart 100 by UTMB, run through the Salzkammergut lake country east of Salzburg. From St. Gilgen it strings together the Wolfgangsee and Fuschlsee shorelines with two big mountain shoulders, packing 4580 m of climbing into a route that tops out at 1721 m. It is not a high-altitude race, but with that much vertical over 84 km it earns its ultra billing. What defines this course is its shape: long, runnable lakeside stretches broken by a handful of steep, concentrated climbs. You pass back through St. Gilgen at 41.9 km, so this is effectively a two-act race — a first loop over the Schafberg massif, then a second, harder push over the Illingeralm before the run-in to Fuschl am See. Managing effort across that mid-race hinge is the whole game.
The Course: Two Lakes and a Return Through St. Gilgen
The race starts in St. Gilgen at 539 m on the shore of the Wolfgangsee and rolls gently for the opening 19 km, passing Abersee (10.3 km, 562 m) and reaching Strobl (19 km, 535 m) at the far end of the lake. This is the flattest, fastest ground on the course and a place to bank time without spending legs. From Strobl the route turns upward onto the Schafberg massif, the iconic peak of the region, before dropping all the way back to St. Gilgen at 41.9 km — the same town you started in, now the crossroads of the day. The second half heads toward the Fuschlsee basin. After the big Illingeralm climb the route descends to Schafbachalm (54.7 km, 1046 m) and continues to Faistenau (69.1 km, 775 m), the last crew point, before a final 14.9 km leg to the finish at Fuschl am See (84 km, 660 m). St. Gilgen, Strobl, Faistenau and Fuschl am See are all crew points, giving support a natural rhythm of roughly every 15 to 22 km through the back half.
Where the Race Is Won or Lost: The Two Big Climbs
The first decisive effort comes out of Strobl: the trail lifts from 535 m to Sommeraualm at 1151 m (25.3 km) and on to the Schafberg shoulder at 1352 m (33.7 km), with the course high point of 1721 m reached on this massif. That is roughly 800 m of climbing in the 6 km above Strobl — steep, sustained, and early enough that overcooking it will haunt the second loop. The long descent off the Schafberg to St. Gilgen sheds over 800 m and pounds the quads; run it under control. The true crux is the Illingeralm climb straight out of St. Gilgen: 538 m up to 1443 m by 49.7 km, a 900 m wall tackled on tired legs at the 42 km mark. This is the single biggest sustained ascent of the day and it comes exactly when the first-loop fatigue lands. Hike it efficiently with poles, keep eating, and treat cresting Illingeralm as the moment the finish becomes realistic. After it, the profile trends downward and rolling toward Faistenau and the lake.
Pacing and Fuelling to the Cut-Offs
The cut-offs tighten as the day goes on, so the free time is up front. Strobl closes at Sat 10:30 and the St. Gilgen return at Sat 16:00, giving a generous window across the first loop — but Illingeralm (Sat 18:30) and Schafbachalm (Sat 20:30) follow quickly, and Faistenau shuts at Sat 22:30 with the finish at Fuschl am See at Sun 04:00. The back half offers less slack per kilometre than the front, which is another reason to arrive at the 42 km return with legs still willing to climb. Plan fuelling around the crew points at St. Gilgen (start and 41.9 km), Strobl (19 km), Faistenau (69.1 km) and the finish. The long climbs to Sommeraualm and Illingeralm are hiking efforts where you can eat steadily; the runnable lakeside and the Faistenau-to-Fuschl run-in are where calories taken earlier pay off. Because the second St. Gilgen pass is both a crew point and the foot of the hardest climb, it is the key resupply of the day — leave it with full bottles and enough food to cover the roughly 8 km to Illingeralm and beyond.
Conditions to Expect
This is an alpine-foothills race in the Salzkammergut, where the weather over the Wolfgangsee and Schafberg can shift quickly even in summer. The high point of 1721 m is modest, but exposed sections on the Schafberg and Illingeralm shoulders can be cold, wet or windy while the lakeshores below stay warm, so pack for a wide range across the 84 km. The mandatory-kit ethos of UTMB events exists precisely for this kind of variability. Timing matters too: with a finish cut-off of Sun 04:00, mid- and back-of-pack runners will spend meaningful time moving in the dark, particularly on the Illingeralm descent, the Schafbachalm section and the final leg into Fuschl am See. A reliable headtorch, spare batteries and warm layers for the night hours are essential, and the descents off both major climbs reward careful footing when tired and visibility is low.
