The Story
Zürich, Switzerland. Olympic-distance triathlon. The 1500m swim sends you into cold freshwater lake at 13°C — bracing — the kind of cold that sharpens focus. The bike covers 40km of rolling with significant elevation terrain with 400m of climbing — enough to test your legs without breaking them. A 10km rolling run through Zürich that punishes anyone who left their legs on the bike. Humidity sits around 79% — the air itself feels like resistance. This is Zürich triathlon: Zürichsee's clean waters, banking-district run, Alps visible on the horizon. Not the longest day in triathlon, but one that leaves a mark.
"People underestimate olympic distance. Come to Zürich and try underestimating it."
What It Feels Like
A olympic course that reflects Zürich: Swiss precision on a lake-and-hills course. It suits a wide range of athletes — accessible enough for a strong first-timer, honest enough to challenge a veteran. Race it once and you'll understand why people return.
🏊 The Swim
A 1500m freshwater lake swim at 13°C. No salt sting, no currents, just you and the distance. Lake swims reward smooth technique over brute force.
🚴 The Bike
40km of rolling terrain with 400m of climbing. Short rises break your rhythm; descents reward those who corner confidently. It's a bike course that asks for constant attention — no long steady stretches to zone out.
🏃 The Run
A 10km rolling run through Zürich. The undulations are gentle but relentless — each small rise costs more than it should on tired legs. Keep your cadence quick on the ups and let gravity help on the downs.
💡 Insider Tips
- → Water temperature averages 13°C. Acclimatise with cold-water swims in training — your first 200m will set the tone for the entire race. A neoprene cap under your swim cap makes a real difference.
- → The bike has 400m of climbing — don't underestimate the cumulative toll on your legs. Keep your cadence high on the climbs and save your quads for the run. A compact crankset with a 28+ cassette is worth considering.
- → For Olympic distance, nutrition is simple but essential. One gel or drink mix on the bike, sipped across the 40km, and one gel at the start of the run. Over-fuelling a two-hour race is as common a mistake as under-fuelling.
