Course description
One of the largest amateur triathlons in Switzerland at Lake Greifensee. A calm 1.9 km lake swim, a traffic-free 90 km bike course redesigned for 2026, and a flat 21 km run along the shore.
Coach tip
The rolling bike course rewards active shifting over constant pressure.
Lake Greifensee is usually pleasantly warm in August.
The run is flat and partly on unpaved paths – choose shoes accordingly.
