Does my registration require a certificate and/or membership?

It depends on the event and the race selected: the organiser decides which documents are needed to take part (medical certificate, membership, both or neither). Usually the registration flow itself tells you whether these documents need to be uploaded.

In any case, documents can also be uploaded after registration - usually up until a few days before the race. If you did not do it during registration, you can upload them or check their status with these steps:

1. Log in to your profile on endu.net.
2. Click on Registrations.
3. If you have more than one registration, select the card of the event you are looking for.
4. Click on My registration.
5. In the Participation requirements section you will find the list of documents required for your registration, their status, and the option to upload any that are missing.

If the section requires nothing, you do not need to upload anything.
