Hikers that participated in the last three years will be notified personally during the month of March as far as the secretary has a complete address. Those people receive an registration number and an OGM number at the same time. They can go for it at once.

Their data is already in a database; with the registration number, they can easily recall the data. So, they can modify, correct or complete the data and the secretariat will be able to serve them better. The registration number is unique, personal and never changes.

Did you ever participate at the Four Days before that period, then, there is a good chance that your data is already in our database (since 1997). You don't know your inscription number, you lost or forgot it ? You can ask for it here! Your inscription number will be sent tot you as soon as possible.

The OGM number(complete, with stars and slashes) is to be used as the communication on the transfer form. It's valid only in 2018 and it permits the secretariat of the Four Days to settle payments automatically and to check for whom the payment was made.

In all other cases, simply follow the on-screen guidelines. After filling out the necessary data and the chosen formula, a registration number and an OGM number (valid only this year) are generated.

Refund on pre-registration fee:
Refunding the pre-registration fee will onlyhappen if an annulation is received at the secretariat of the Four Days of the Yser before 20 August 2018.
If any cancellation is made afterthis date, the transport costs will not be refunded.
