What is the British OCR Ultra Championship?
The inaugural British OCR Ultra Championship will take place during the Spartan London South East Ultra on October 4th, 2025.
Who is eligible for the British OCR Ultra Championship title?
All British citizens and residents registered for the Spartan London South East Ultra will automatically be entered into the British OCR Ultra Championship.
Placings and awards will be given separately from the standard Spartan Elite and Age Group results.
What if I’m not a British citizen or resident?
Non-British competitors can still register for the Ultra’s Elite or Age Group heats and may place in Spartan’s regular podium rankings. However, they will not be eligible for British OCR Ultra Championship awards.
IMPORTANT: To compete in the Elite or Age Group heats at any UK Spartan event in 2025, you must hold one of the following:
-
A British Obstacle Sports (BOS) Membership, or
-
A valid membership with your home country’s Obstacle Sport Federation.
What if my country doesn’t have an Obstacle Sport Federation?
British Obstacle Sports offers a Day Membership for athletes whose home country does not have a federation, or for those who prefer not to purchase a full annual membership.
