Supertri Blenheim Palace will host a stage of the British Triathlon Super Series on June 7, 2026. The event will be integrated into the Supertri Pro Series, bringing together international professional athletes and UK-based elite competitors on the same course.
The collaboration with British Triathlon aims to support the growth of the sport and provide development opportunities for elite athletes. British competitors will have the chance to qualify for the Supertri Pro Series Final, which features a total prize pool of more than US$800,000.
The Supertri Pro Series race at Blenheim Palace is part of a broader weekend of racing on June 6–7, 2026. The event, organised by Supertri, allows amateur participants the opportunity to compete on the same course and over the same distances as the elite fields.
Pro Series events are draft-legal, sprint distance races. In an effort to encourage development within the sport, prize money is awarded to the top 10 finishers. Athletes competing in the British Triathlon Super Series will be eligible for both Super Series and Supertri Pro Series podiums and prize funds.
Under the qualification rules, three athletes per gender will secure a spot in the Supertri Pro Series Final through the Blenheim Palace event.
The 2026 Supertri Pro Series schedule includes:
- Ascension Seton Supertri Austin, TX – May 25, 2026
- Supertri Blenheim Palace, UK – June 7, 2026
- Supertri Toronto, Canada – July 26, 2026
The date and location for the season final are expected to be announced in the near future.
British Triathlon’s Super Series consists of six events staged across the 2026 season. British elite athletes can register their interest in the series via the national governing body.
Supertri, formerly known as Super League Triathlon, specialises in high-intensity, spectator-friendly triathlon formats. Its international circuit is designed to bridge the gap between amateur participation and professional racing.
Amateur entries for the weekend at Blenheim Palace remain open for those wishing to compete at the UNESCO World Heritage site.
