What’s the difference between an own place and a charity place? (Scroll down for explanation)



Own Place

I have secured a place through the official ballot but wish to run for OCD-UK.


If you experience any issues with the registration forms, please get in touch with us:

Charity place:

If you have not entered the ballot in the official event, or if you did enter and have been contacted to say you were unsuccessful in the ballot results, then this option it for you. OCD-UK has guaranteed charity places and therefore by clicking ‘Charity Place’ you will be offered a guaranteed place in the event. We ask for a registration fee to be paid and once we receive this we will send you a welcome pack which will include an OCD-UK fundraising T-shirt. 


Own place:

If you have entered the ballot in the official event, via their own website, and they have contacted you to say you have a place in the event, then this option is for you. By clicking on ‘Own place’ you are choosing to fundraise for OCD-UK, and you will be taken through the steps to create your fundraising account. OCD-UK will take some details so we can send you a welcome pack in the post with an OCD-UK fundraising T-shirt. This option is free because you already have a place and we don't request any minimum fundraising amount.
