You can change the distance you have registered for via My 4Days. You can make the change without charge up to the end of the week before the 4Days Marches event starts. After this date, changes to the distance can only be made on Sunday 16 or Monday 17 July at the Service Desk at your starting location,, for a €15 fee.
A change to the military 40km route that starts from Heumensoord can only be made if you have also booked a stay at Camp Heumensoord. This is possible until 16 June via My 4Days.
Please note that once the 4Days Marches has begun, you can no longer change the distance you will be walking. You must then walk the full distance you are registered for on each of the four days.
