That was the 4th Zurich City Triathlon – a weekend full of highlights.

The Zurich City Triathlon 2025 was a great success: With over 5,000 participants, a new record was set – making ZC3 once again the largest triathlon in Switzerland.

On Saturday, the free Kidstriathlon brought big smiles to over 200 children. Sunday followed with the main race day featuring individual, team, and corporate starts. A particular highlight: the Company Triathlon, where 760 teams competed for the title of “the fittest company of switzerland” – which was won by SWISS RE.

Top-level racing was also on display: The Swiss Championship titles went to Julie Derron and Adrien Briffod.

Thousands of spectators along the course and at Landiwiese made ZC3 a thrilling experience – despite the intense summer heat.

📅 The next Zurich City Triathlon will take place on June 27–28, 2026 – we’re already looking forward to it!
