Internationaler Sparkassen Hallstättersee Rundlauf Training Plan & Preparation

Course & Elevation

With 102 metres of climbing over 21.1 kilometres, the Hallstättersee Rundlauf ranks among Austria's flat half marathons. Nearly two thirds of the distance is completely level, and the remainder splits into mild ups and downs without a single steep spot. What structure the profile does offer comes down to three features: a short wave around kilometre 5.9, a rise of roughly 20 metres between kilometres 12 and 13.3, and a drawn-out, shallow ramp from kilometre 15.5 up to the highest point of the course around kilometre 18.

Geographically the race is one complete circuit of the lake. It starts at Hallstatt-Lahn towards Obertraun, follows the eastern shore through Obersee and Untersee to Steeg, and returns along the western side via Gosaumühle to Hallstatt, where the finish arch stands on the market square. The flattest running comes between kilometres 9 and 12 right beside the water, and five aid points line the route, including Obertraun, Obersee, Steeg and Gosaumühle.

The race carries decades of tradition in the Salzkammergut, and its organizers call it the country's most beautiful half marathon — the combination of lakeshore, mountain backdrop and a finish in a World Heritage town explains why the field draws runners from well beyond the region.

Pacing Strategy

The danger on this course lies less in the profile than in your head: the route is quick and the first third only rolls gently, so plenty of runners open above their limit. Stick to your goal pace in the early phase rather than to groups — whatever you force in the first five kilometres will be missing along the western shore. The wave at kilometre 5.9 is short and settled with calm, steady effort; after it, the level lakeside stretch from kilometre 9 to 12 offers the cleanest opportunity of the race to stay in rhythm and fuel properly.

The rise between kilometres 12 and 13.3 costs around 20 metres — climb it under control and let the descent towards Steeg bring you back up to speed for free. The race is decided on the long, barely visible drag between kilometres 15.5 and 18: whoever still has reserves there can accelerate all the way into Hallstatt, because from the high point the road trends gently downhill — only a last small counter-rise at kilometre 19.5 stands in the way.

12-Week Preparation

The demand profile of this half marathon is unambiguous: a steady aerobic effort of roughly one and a half to two and a half hours with no anaerobic spikes, because the lake circuit simply has no steep ramps. Preparing for it means developing a pace you can hold for the full distance, not training for mountains.

Anchor the week around two priorities: threshold work that stabilises your race pace from below — intervals of ten to twenty minutes at threshold, or tempo runs in your goal range — and a long run that grows towards 18 to 22 kilometres. Since nearly two thirds of the course is level, most tempo sessions belong on flat ground; the course's small waves are best mirrored by routing part of your easy runs over slightly rolling terrain and holding effort constant instead of attacking every crest.

The race-deciding section starts at kilometre 15.5: a long, shallow rise arriving exactly when fatigue is highest and concentration starts to slip. Train that scenario deliberately with progressive long runs whose final three to five kilometres finish at race pace.

A late-April race date implies a winter build: base mileage through the dark months, quality from late winter onwards, and two calm weeks before the start. Test your race fuelling in advance as well — the course offers five aid points, and at this distance a simple, rehearsed routine is enough.
