Registration now open for 2026!

We are delighted to announce that registration for the 2026 O.K. 10k is now open!

Following the huge success of last year’s event, which sold out in just a few weeks, we’re excited to be able to offer more places this year, giving even more people the chance to take part. Please share this with your family, friends and colleagues and encourage them to register and join you.

The O.K. 10k takes place against the backdrop of the stunning Cornbury Park, in the Cotswolds. This amazing route winds through a private estate that is not normally open to the public with access to the ancient Wychwood Forest, making it a truly special and unforgettable experience.

Our mission remains unchanged: a fun, inclusive 5k or 10k walk or run for all ages and abilities, raising awareness of Neuroendocrine Cancer and vital funds for research into this rare disease.

Not a runner or walker but still want to be part of the day? We’d love to have you join us as a volunteer. Volunteers are essential to making the event happen, and you can register your interest in volunteering via this link.

We hope you’ll join us this year for the 2026 O.K. 10k—places are expected to fill quickly, so don’t miss out and register now!
