Please make sure to copy and paste your registration number to avoid mistakes such as confusing the number "0" with the letter "O". Also double-check that there are no spaces before or after your registration number. Lastly, make sure that your Active Profile information, such as your full name (no nicknames or shortened names), email address, and date of birth are all an exact match to the information on your ticket.
If you continue to have an issue or receive an error message, and you need to complete an action that requires your registration to be claimed (transfer, purchase add-ons, view registration, etc.), please contact UKsupport@toughmudder.com with the following information:
1. Registration ID (R-********)
2. The event you are registered for
3. The error message you are receiving (a screenshot of this will be very helpful as well).
