Triathlons in the Greater Zurich Area

Lake Zurich is the region's number one asset: about forty kilometers long, with water known for its cleanliness and swimming areas set up almost everywhere 🏊. Zurich locals swim in the lake, but also in the Limmat, in the heart of the city, a summer ritual that surprises visitors. For a triathlon in the Greater Zurich area, nobody is afraid of the swim.

On the bike, the route runs along the lake shores before climbing toward the Pfannenstiel or the Albis, honest hills that build strong legs 🚴. The run then takes place on flat paths along the water. The season opens in May, when the lake temperature becomes bearable, then peaks in June and July. The city's outdoor pools, open in the summer, serve as training before heading into open water.

The region's triathlon calendar revolves around one big name: the Ironman 70.3 Switzerland, scheduled for June 6, 2027 in Rapperswil-Jona, at the tip of Lake Zurich, in the canton of St. Gallen 🏁. The 70.3 format combines a 1.9 km swim, a 90 km bike ride and a 21.1 km run, and attracts athletes from all over Europe. For an overview of the city, the triathlons in Zurich page completes the picture.

Rapperswil-Jona calls itself the town of roses, with its castle overlooking the lake and its pedestrian old town 🌹. Triathletes find a postcard setting for a race day. Between two sessions, Zurich locals head to the water's edge to recover, towel over their shoulder. From the first sprint to the long distance, everyone chooses their format according to their level and their appetite for a challenge, with the lake as a training partner.
