How do I change my entry details?

You can change your address, estimated time or t-shirt size by clicking on the “Manage your registration” button in your Let's Do This confirmation email. You can also add postage if you are no longer able to collect your race pack on the Friday or Saturday before the event.

This can only be done until 29 January 2026. 

If a field, such as t-shirt size, is greyed out it is no longer possible to change this detail. 

It is not possible to change your name or email address yourself. If you need to update your email address please contact us. 

If you would like to give your entry to someone else please use the official Transfer System, which can also be found by clicking on "Manage your registration".
