Supertri has acquired Blenheim Palace Triathlon in the UK and New Jersey State Triathlon in the US, two of the world’s largest triathlon events. These acquisitions are part of Supertri’s strategy to scale its mass-participation portfolio and build a global calendar of triathlon experiences.
Blenheim Palace Triathlon is the biggest triathlon in the UK and is staged in the grounds of Blenheim Palace, Oxfordshire, a UNESCO World Heritage Site since 1987 and the birthplace of Winston Churchill. The 2025 edition in June sold over 7,000 entries, with 33 percent first-timers. In addition to being a historic venue, Blenheim Palace hosts a variety of events, themed tours and exhibitions throughout the year.
The New Jersey State Triathlon was created in 2006 and is held annually in Mercer County Park. It is one of the ten largest triathlons in the US. The 2026 edition will be held on July 19, the same weekend as Supertri’s flagship Long Beach Triathlon in California.
