Jersey
21 September 2025
Supertri will make an emotional return home to Jersey this year, bringing its world-class Supertri League race back to the island on Sunday 21st September.

A standout Destination
Renowned for its electric atmosphere, community support and dramatic coastal setting, Jersey has long been one of the standout destinations on the Supertri calendar and will become the first ever city to host five Supertri League events.
Jersey was the first venue to host a full Supertri event back in 2017, and hosted further events in 2018, 2019, and the COVID delayed 2021 event that concluded its former contract. Now Supertri League is back and promises to build on that legacy, delivering an unforgettable sporting spectacle while continuing to drive meaningful impact for the island.

Inspiring An Active Jersey
The return of Supertri aligns with Jersey’s ‘Inspiring an Active Jersey (2020-2030)’, which aims to create a healthier, more productive and fairer society by becoming one of the most physically active populations in the world.
In previous years, the event increased junior triathlon club membership by 3.5 times and earned the pride of the island - 84% of Jersey residents surveyed in 2019 said they were proud to host Supertri.
