Thuner Stadtlauf: Course, Route Profile & Map

Course & Elevation

The start is in the Aarefeld. The course runs through the Schadaupark and across the Kleist Inseli onto the Aarequai and follows the river out to Hilterfingen, where it turns. Across those first 8.7 kilometres the elevation moves between 558 and 560 metres – not an almost-flat course but a flat one, and it stays at the water essentially the whole way.

Back in town the route takes in Mühleplatz, Bälliz and Marktgasse before the only climb of the day: from kilometre 8.85 the course gains about 30 metres over a good 400 metres of running, averaging a little over seven percent and touching 17. Reaching the Schlossberg does not end the race either – the same 30 metres go back down through the Obere Hauptgasse to the finish.

The interplay of those two worlds is what gives the race its character: the open, bright riverside quay on one side, the narrow old town with the castle-hill ramp and the finish area on the Rathausplatz on the other. It is run on a Saturday evening in August, in 2026 for the 31st time, organised by the Verein Thuner Stadtlauf, and it finishes in the middle of town where the refreshments are.

Pacing Strategy

On a course that is more than 80 percent flat, the pace is not dictated by the terrain but by you. That sounds comfortable, but it is the harder job: across 8.7 kilometres on the Aarequai there is no reason to change pace, and no excuse either if it was too high. The turnaround at Hilterfingen is the one natural checkpoint in the race – arriving there ahead of plan does not mean you felt good, it means you invested too early.

The race is decided on the Schlossberg. After 8.7 flat kilometres, a ramp of over seven percent meets legs that have repeated the same movement for half an hour. Trying to hold pace up it is the wrong approach; those two to three minutes are governed by effort, with shorter steps and a higher cadence. The descent through the Obere Hauptgasse to the Rathausplatz follows immediately – short, steep and to be run on heavy legs.

The classic trap is the group on the quay. On open, level ground it is easy to sit with a pack running two seconds per kilometre too fast; on the flat that costs almost nothing, on the castle-hill ramp it costs everything. The Aarequai is also open and unsheltered, so a headwind on one half of the out-and-back can become a genuine factor – and then even effort counts for more than the watch does.

Training plan for Thuner Stadtlauf: 12-week build

For age-group runners the 10 kilometres take roughly 40 to 60 minutes. For most of that the demand is an uninterrupted threshold effort: hardly any descent to recover on, hardly any rise to break the rhythm. That makes the ability to hold one pace over a long stretch more relevant here than on a hillier 10 km.

The closing section then asks for something else. The Schlossberg climb lasts two to three minutes well above threshold depending on your level, followed immediately by a steep descent to the finish. Short hill repeats of 300 to 500 metres at seven to ten percent, consistently placed at the end of a tempo run, fit the demand, along with some deliberate downhill running so the quads know the switch from climbing to descending in a fatigued state.

The conditions are predictable without being harmless. A Saturday evening in late August often still brings summer temperatures, and the Aarequai lies open at the water, where wind arrives unbroken. Some of the tempo work should therefore be done in warm weather and on open ground without shelter. The surface changes from asphalt quay to the paved lanes of the old town with kerbs and edges, which argues for flat, grippy racing shoes.

The build accordingly rests on two pillars: sustained speed on the flat, through longer runs at goal race pace or intervals of 2,000 to 3,000 metres, and the readiness to run one short, hard climb after 45 minutes of that single effort. A session combining both – a tempo run with a hill effort tacked on at the end – reproduces the race most closely.
