Zurich City Triathlon: Course, Route Profile & Map

Course & Elevation

The start is in Lake Zurich directly off the Landiwiese in Zurich Wollishofen, one swim lap of 1.5 kilometres. At the end of June the water in the lake basin normally sits around 20 degrees, so a wetsuit swim is the rule. The exit leads straight into transition on the meadow.

The bike leg is two identical laps of 20 kilometres. It runs north along the Mythenquai, around the head of the lake basin on the General-Guisan-Quai, across the Quaibrücke and then down the eastern shore on Utoquai, Bellerivestrasse and Seestrasse through Tiefenbrunnen and Zollikon to a turnaround just beyond Küsnacht. A short inland spur over the Alfred-Escher-Strasse and through the Ulmbergtunnel completes the lap. The roads are closed and drafting is not allowed. The whole lap sits inside an altitude band of about 25 metres; there is no climb in any real sense.

The run is two laps of 5 kilometres on the lakeside promenade along the Mythenquai, across the Quaibrücke and a stretch of the Utoquai before turning back. The finish is on the Landiwiese. Because the lap runs right through the city's lake basin, almost the whole run is lined with spectators, and since both distances use the same quays the course stays busy all day.

Pacing Strategy

On a course without a single climb and with drafting banned, your own pacing is the entire race. There is no group to share the work and no gradient to structure the effort from outside. Swim the 1.5 kilometres deliberately evenly rather than for position: a hard opening to the first buoy costs more over the following 40 kilometres of solo riding than it ever gains in the water.

The race is decided on the second bike lap. The first one rolls almost by itself on closed, flat roads, which is exactly why so many riders go out too hard. Fix a power target for the return from the Küsnacht turnaround and hold it even while being passed. The four turnarounds per lap, plus the Ulmbergtunnel and the Quaibrücke, each demand a re-acceleration from low speed; taking them smoothly and braking early saves more across two laps than any aero position adds.

The trap is the open lakeside. The stretch between Tiefenbrunnen and Küsnacht is fully exposed to the water, and an afternoon northwesterly turns one direction into a time trial and the other into recovery. Ride to power, not to speed, or you will ride the return leg too hard. On the run the decision comes in the third kilometre, when your legs leave the cycling rhythm and the lap is already familiar: short steps, high cadence, and only open the pace up after the first turn.

Training plan for Zurich City Triathlon: 12-week build

The Olympic distance in Zurich takes roughly two to three hours depending on your level. The demand is a long, even aerobic effort punctuated by many short re-accelerations: the course is flat, but the turnarounds, bridges and quayside bends keep interrupting the rhythm, and with drafting banned every one of those accelerations has to be paid for alone.

What decides it is the ability to hold steady power near threshold for 40 kilometres and still run 10 flat kilometres afterwards. No section of the course forces any recovery, so discipline on the bike determines what is left for the run.

Conditions belong in the preparation. At the end of June the lake basin is normally around 20 degrees and race days are warm and sometimes humid. Open-water sessions in a wetsuit at those temperatures, a rehearsed drinking routine on the bike and at least one hard session in the heat of the day are well spent. The exposed lakeside stretch also makes riding in wind a discipline of its own.

The training emphasis therefore belongs on long threshold blocks on the bike, two to three efforts of 20 minutes just under threshold, ideally on a flat loop with real turnarounds rather than indoors, plus sets of short accelerations from low speed. Add a weekly brick run of 15 to 25 minutes at goal race pace and flat tempo runs of 3 to 5 kilometres, because across 10 kilometres with no profile nothing counts but running speed under pre-fatigue.
