What is my registration number and where can I find it?
When you register for the 4Days Marches for the first time you will be allocated an unique and personal registration number that will be linked to your name and other data. This registration number consists of a maximum of six digits. When you do not know your registration number you can request it at My 4Days. Please state this number when you register or when you contact us. This way we can retrieve your personal details and previous participations and help you in a sufficient manner.
