You can change the distance you have registered for via My 4Days. Changing your distance is free of charge until Thursday 13 July. After this date, changes to the distance can only be made on Sunday 16 or Monday 17 July at the Service Desk at the start and finish location, for a €15 fee.
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.
