Supertri Expands Global Footprint with Acquisition of Blenheim Palace and New Jersey State Triathlons

LONDON, UK – 15th September – Supertri has today announced the acquisition of two of the world’s most significant triathlon events – Blenheim Palace Triathlon in the UK and New Jersey State Triathlon in the US – as part of its strategy to scale its mass-participation portfolio and build a global calendar of landmark triathlon experiences.

The addition of Blenheim Palace Triathlon means Supertri now owns two of the five largest triathlons in the world, alongside the already established Chicago Triathlon. The 42nd Chicago Triathlon took place in August with a record-breaking 8,000 participants including 800 kids.

The acquisition of the New Jersey State Triathlon builds on Supertri’s strategy to build a calendar of landmark mass-participation events in North America to reinforce a true coast-to-coast footprint with Chicago, Long Beach, Austin, Kerrville and Toronto already part of the Supertri family.

Michael D’hulst, Supertri Co-Founder and CEO 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.”

Blenheim Palace Triathlon, the biggest triathlon in the UK, staged for over two decades on the UNESCO World Heritage Site and birthplace of Sir Winston Churchill, is known for its breathtaking backdrop, inclusive race formats and friendly atmosphere.

The event offers Sprint, Super Sprint and Relay formats, as well as the unique Weekend Warrior Challenge, where athletes test their endurance by completing as many triathlons as possible over the weekend. The 2025 edition at the beginning of June sold over 7,000 entries, with 33% first-timers, highlighting the race’s strong appeal among beginners and its reputation as one of the UK’s most welcoming and inclusive events.

The New Jersey State Triathlon, held annually in Mercer County Park, is one of the ten largest triathlons in the United States and has consistently sold out its 3,500 slots since its inception in 2006.

Known for its flat and fast course, the event features Sprint and Olympic distance races and draws athletes from across the country looking for personal bests and high-energy race day experiences. The 2026 edition will take place on 19 July, the same weekend as Supertri’s flagship Long Beach Triathlon, further strengthening the brand’s coast-to-coast presence in the US.

Jonny Brownlee, the three-time Olympic medallist who was a joint winner of Blenheim Triathlon alongside brother Alistair as they prepared for glory at London 2012, said: "Blenheim Triathlon is a fantastic event that I have been lucky enough to race and to win in the past. It’s one of the most iconic races in the UK, with a huge number of participants and is in an incredible setting in the grounds of Blenheim Palace. I’m delighted that Supertri has acquired the event. They are doing so much to develop triathlon and to get more people interested in the sport both with their professional racing and their mass participation events and I am sure they will grow this event further and it will have a huge impact on the sport in the UK."

Michele Redrow, co-founder of the New Jersey State Triathlon, added: “We’re excited to see the New Jersey State Triathlon join the Supertri family of high-quality events. We look forward to working closely with their team to ensure the race continues to deliver the unique elements that make it so special to the triathlon community.”

These acquisitions align with Supertri’s broader mission to deliver world-class race production with a community feel, from first-timers to elite amateurs, and to inspire the next generation of triathletes.

Alongside its mass-participation events, Supertri also runs the professional Supertri League – featuring some of the sport’s biggest names, including Olympic gold medallists Alex Yee, Cassandre Beaugrand and Jonny Brownlee – and the innovative Supertri E World Championships.

Supertri’s business expansion is supported by Astero Partners, with Alexis Nohen serving as an advisor for the acquisitions.

Any existing entrants to the 2026 Blenheim Palace Triathlon and New Jersey State Triathlon will have their entries automatically transferred.
