The NAF Hartpury International Celebration of Eventing, including the British National Championships, will take place from August 11-16, 2026, at Hartpury University and College. A major change for 2026 is the elevation of the British Open Championship to CCI4-S level, integrating it within the NAF CCI4-S class. This new format means the British Open will be contested on the same course and schedule as the international competition, with the overall CCI4-S winner also crowned British Open Champion where eligible. The championship, held on Saturday, offers an enhanced £2,500 winner’s prize in addition to the CCI4-S purse, making it a highly prestigious and lucrative event.

Hartpury, awarded the Championships for the next five years in partnership with NAF, is committed to growing the event through rider and owner collaboration and significant investment. Organizers aim to create a clearer, more competitive, and visible championship that culminates in a standout moment for both riders and spectators. The event promises a knowledgeable crowd, strong competitors, and a family-friendly atmosphere, reinforcing its status as a world-class stage for British eventing with the British Open Championship at its heart.
