Race guide
Updated 19 July 2026
The Mozart 100 by UTMB is a 119-kilometre point-to-point ultra running from Fuschl am See to a finish on Salzburg's Kapitelplatz, threading through the lakes and alpine ridges of the Salzkammergut. With 5649 m of climbing and a high point of 1721 m, this is a genuine mountain hundred — not an extreme altitude race, but one that demands respect for its relentless terrain and the cumulative fatigue that builds across its second half. The route links iconic lake villages — St. Gilgen, St. Wolfgang, Strobl — before looping back through Fuschl am See at kilometre 85 as a life base, then pushing into the hills above Salzburg for a final push into the city. The cultural finish on Kapitelplatz, in the heart of Baroque Salzburg, is one of the most distinctive arrivals in the UTMB World Series.
Course & Terrain
The race opens at Fuschl am See (654 m) and trends south and east through the Salzkammergut lake district. The first 32 kilometres to St. Wolfgang climb steadily to 1318 m — a sign of things to come — before the course winds through Postalm at kilometre 50 (1029 m) and drops into Strobl at kilometre 64 (1086 m). The terrain throughout mixes forested singletrack, alpine meadow trails and occasional technical rocky sections as you gain and lose the ridgelines above the lakes. After the life base at Fuschl am See (km 85, 649 m), the character changes: the trail climbs back into the hills above Hof bei Salzburg (km 97, 982 m), and the final 22 kilometres negotiate the transition from mountain terrain to the outskirts of the city before delivering runners onto Kapitelplatz. Surfaces range from soft forest floor and grass to harder packed trail and some technical alpine ground near the high point of 1721 m.
The Decisive Climbs — Where the Race Is Won or Lost
Two sections define your race. The first is the prolonged climb to St. Wolfgang at kilometre 32 — arriving at 1318 m, this is the highest checkpoint on the course and the first real test of leg management. Runners who push the uphills here to 'make time' arrive at Postalm already compromised. The second defining passage is the climb out of the life base at Fuschl am See (km 85) back up toward Hof bei Salzburg at 982 m. By this point you have 85 kilometres in your legs; any deficit in pacing or fuelling from the first half is fully exposed on this climb. The kilometres between Hof bei Salzburg and Salzburg Kapitelplatz — the final 22 km — are where races are decided: the cut-off at the finish is Sunday 04:00, which creates real time pressure for mid-pack runners who have bled too much time in the middle of the course.
How to Pace It
The cardinal error on Mozart 100 is treating the lake-valley sections as flat bonuses and attacking the early climbs. The opening 50 kilometres — despite the climb to St. Wolfgang — feel comparatively manageable and the scenery actively encourages you to push. Resist it. A patient, almost social first half is not wasted time; it is the deposit that funds a strong close. Run the uphills at a controlled effort you could sustain for another hour, and arrive at each crew point — St. Gilgen (16 km), St. Wolfgang (32 km), Strobl (64 km) — feeling like you have more left than you need. The life base at kilometre 85 is the pivot: use it efficiently for a full reset — feet, kit, food — then shift mentally into race mode for the final 34 kilometres. Break the closing section into manageable chunks rather than fixating on the total remaining distance; 'two more climbs and I'm in the city' is a more useful frame than counting kilometres. The record on this course was built on restraint early, not aggression.
Fuelling & Checkpoints
With crew access at six of the eight checkpoints — St. Gilgen (16 km), St. Wolfgang (32 km), Strobl (64 km), Fuschl am See life base (85 km), Hof bei Salzburg (97 km) and the finish — you have excellent opportunities to resupply with real food and swap kit. Postalm at kilometre 50 is the only non-crew checkpoint in the main body of the course, so plan your carry from St. Wolfgang to cover the 32 kilometres to Strobl with a stop at Postalm in between. Caloric needs are substantial: 5649 m of climbing over 119 km demands consistent fuelling from the gun, not just in the second half when appetite typically drops. Prioritise liquid intake through the warmer middle hours and use the crew points to take on food you know you can stomach rather than relying solely on whatever is provided on course.
Conditions to Expect
The Salzkammergut is known for changeable alpine weather, and the Mozart 100 course sits in terrain that can deliver sunshine, rain and cold ridge winds within the same day. The high point of 1721 m is not extreme by alpine standards, but exposed sections near the summit can be significantly colder and windier than the valley stages, particularly if the race moves through those sections at night. Carry a proper waterproof and a mid-layer regardless of the forecast. The lake-district valleys tend to retain heat and humidity during summer race conditions, which makes the valley running — particularly the middle sections around Strobl and the return to Fuschl am See — more taxing than the elevation profile suggests. Night sections are a near certainty for most runners: the finish cut-off is Sunday 04:00, meaning most of the field will run through at least one full night. Prepare your lighting kit accordingly and know your pace well enough to stay ahead of the cut-off across the final 22 kilometres into Salzburg.
