Tägi Tri & Duathlon: Course, Elevation & Route Profile

Course & Elevation

The swim goes off from eight o'clock in the 50-metre outdoor pool of the Tägi Wettingen: ten times 100 metres, started in three waves. No open water, no buoys, but wall turns and a very short route into transition.

The bike lap starts on the valley floor at around 406 metres and stays moderately rolling to kilometre eight. From kilometre 8.5 comes the climb that defines the course: 2.45 kilometres at 3.8 per cent on average with peaks to 7.6, up to 526 metres around kilometre 11. The route then drops briskly to about 410 metres and runs flat back to transition. The long distance rides this lap twice, so the climb returns at kilometre 26.5. Riding is on open country roads in the Limmat valley, with helmets compulsory.

The run is then a different kind of ground: two laps of a 3.9-kilometre loop on riverside paths and green space along the Limmat. Each lap drops from 406 to 387 metres in the first kilometre, climbs back to kilometre 3.2 and undulates to the lap's end. Barely 47 per cent of it is genuinely level, so no rhythm ever settles over several kilometres. The race is staged for the 33rd time, with start and finish at the Tägi; the long distance is open from 18.

Pacing Strategy

A thousand metres in the pool are long enough to overcook, and 10 times 100 invites you to swim them like a training set. Swim them as one piece instead: evenly, with calm breathing and clean turns, because the bike opens immediately with eight rolling kilometres and gives you no time to recover.

The climb decides the race: more precisely, its second pass. 2.45 kilometres at just under four per cent sit clearly above sustainable output for most people when ridden at race effort, and the mistake almost always happens the first time. Ride the first lap's climb deliberately conservatively, seated and at steady cadence, so that the second lap still produces the same time. The descent afterwards is the race's only genuine recovery; use it to drink and loosen off rather than to win time back.

The trap is the run course, because it looks more harmless than it runs. The first kilometre drops, which fakes a pace that feels sustainable off the bike, and then the path rises gently for two kilometres, every lap. Run the first lap to effort rather than to your opening kilometre split, and lift only on the final rise of the second lap.

Training plan for Tägi Tri & Duathlon: 12-week build

For the long distance at the Tägi Tri, expect roughly two to two and three quarter hours depending on your level. The demand splits clearly in two: an evenly hard pool swim; a bike leg with two longer stretches above threshold and two descents as recovery; and a run that is classified flat but consists for more than half its length of gentle rises and falls.

The second pass of the 2.45-kilometre climb at bike kilometre 26.5 and the second run lap decide it. Both are sections that reveal whether the first half was paced correctly, and both come so late that correction is no longer possible.

The conditions are predictable and still distinctive. The swim is in an outdoor pool, so without wetsuit buoyancy, without any sighting task and with twenty turns; outside, mid-August in the Limmat valley is still cool early in the morning, while the second bike lap and the run already fall into the warmth. The bike course stays open to traffic, so drafting is not an option and road rules apply.

Three priorities follow. First, hill intervals on the bike of eight to twelve minutes on gradients around four per cent, ridden at race effort and in pairs with a descent between them, because that exact sequence comes up twice. Second, brick runs on rolling riverside terrain rather than the flat, with a deliberately controlled downhill first kilometre. Third, continuous 1,000-metre pool swims at race effort plus turn technique, because over 20 lengths every turn counts.
