Supertri Blenheim Palace 2026 Preview Includes “First Timer Programme”
Supertri Blenheim Palace 2026 is set to return as the UK’s largest triathlon festival, taking place at the UNESCO World Heritage site in Oxfordshire this summer. The event, scheduled for June 6–7, will host approximately 7,000 amateur and elite participants racing through a 750 m swim in the palace’s Great Lake, followed by cycling and running segments through the historic grounds (triathlon.mx). The event introduces a “First Timer Programme,” offering a free 12‑week personalized training plan and race‑day support aimed at helping complete beginners through the experience (triathlon.mx). While not specific to Premier Tri, the timing and location of the festival may present competitive and participation opportunities for clubs in London and surrounding regions.
