Registration military detachments
We are so pleased that you want to take part in this year’s 4Days Marches! The 105th 4Days Marches will take place from 18-21 July 2023 and the registration fee is €109. You can register for the 4Days Marches online. There will be two registration periods in 2023. Check carefully in which period you can register.
Period 1: from Monday 23 January 2023 (10.00 hrs CET) until Friday 10 February (10.00 hrs CET)
For anyone who wants to participate in the 4Days Marches in a detachment in 2023. All group participants will be registered by the detachment commander (detco).
Period 2: from Monday 13 February 2023 (10.00 hrs CET)
For anyone who wants to participate in the 4Days Marches in 2023 in a detachment and has not yet registered in period 1.
Registration will close when the maximum number of participants has been reached. Everyone has the chance to register in period 2 if the maximum number of participants in period 1 has not been reached. The maximum number of Dutch military participants is set at 1950 and for Small Contingents at 500. There will no longer be a draw.
International military participants who have the nationality of one of the official delegation countries named below are not permitted to use the registration module on this website. They may only register via their delegation's contact person:
All international military participants who don't belong to the military forces of one of the official delegation countries mentioned above, are considered to be participants of the Small Contingents.
Dutch military participants
Military participants with the Dutch nationality can also register online. Please visit the Dutch version of this page for more information about registration as a Dutch military participant.
Would you like to participate in the 4Days Marches with a detachment? Then the detco will register you. A detachment consists of a minimum of 11 and a maximum of 41 participants. It is important that the detco has the name, date of birth and registration number of all participants in the group. From 23 January, you can register on this page.
Step 1: the detco creates a detachment using the form
Enter the registration number of the detco, and enter a detachment name.
Step 2: forming the detachment
Log in to My 4Days and select the previously created detachment. Add the detachment members one by one. You will need the registration number, date of birth and any KWbN membership number. Select per participant if they wish to order a certificate.
Step 3: creating tickets
A detachment must consist of at least 11 people. Complete the detachment registration by clicking the 'Create tickets' button. The detco will receive an email confirming the registration and an invoice.
Step 4 (optional): adding detachment members afterwards
It is possible to add participants to the detachment later. Go to the detachment in My 4Days and add participants. These can be new participants or participants who are already individually registered to the 4Days Marches. Confirm the new detachment by clicking 'Create tickets'. The detco will receive a new confirmation and additional invoice. The invoice only shows the newly registered participants and not those who have already paid for their ticket individually.
Participation as a detachment is subject to a number of additional conditions. Firstly, all detachment members are expected to stay at Camp Heumensoord. All detachments also start from Heumensoord and therefore walk the military 40 km route. Depending on your age and gender, you can walk this route with or without 10 kilos of marching kit. You can read more about this on the Distances page.
You can find more information about the conditions that a detachment must meet to participate in the 4Days Marches in the Regulations for military participants.
