Supertri, the global triathlon series, has bolstered its mass participation events portfolio with the addition of the UK’s Blenheim Palace Triathlon and the US’ New Jersey State Triathlon.
From the 2026 campaign and onwards, Supertri’s mass participation race brand ‘By Supertri’ will be bolstered by the two races, particularly the Blenheim Palace Triathlon, which the brand says is one of the world’s five largest triathlons.
The Blenheim Palace Triathlon is the second of that five that Supertri has acquired, after the Chicago Triathlon, while the New Jersey State Triathlon is now Supertri’s sixth mass participation event in the US.
Initially focused on short-course events, Supertri launched ‘By Supertri’ earlier in 2025, and has since worked to expand its mass-participation event portfolio.
Speaking on these latest two acquisitions, Supertri co-founder and chief executive Michael D’hulst said: “Our vision is to build the leading global brand for short-course triathlon - one that stands for quality, great race experiences, and strong community connections. Blenheim and New Jersey deliver exactly that and represent everything we want our brand to stand for.
“These acquisitions advance Supertri’s plan to build a global calendar, which already includes landmark races such as the Chicago, Long Beach, Toronto, and Kerrville Triathlons.
“Athletes racing in Blenheim and New Jersey will also become part of Supertri’s wider ecosystem - connected year-round through community, content, training pathways, and the organisation’s Esports platform.”
Earlier in 2025, Supertri agreed an expanded global broadcast partnership with media giant Warner Bros. Discovery, ensuring that live coverage of all Supertri League events in 2025 would be shown to an international audience, including in the US on the HBO Max streaming service.
In 2024, it is claimed that more than 6 million watched the Supertri League event in Toulouse, broadcast on Eurosport, and around 55 million global broadcast viewers tuned in across 145 countries.
Two elite professional Supertri League events remain in Supertri’s 2025 calendar, the Supertri Jersey2025 on the titular channel Island, and the Supertri Toulouse 2025 in France.
