Map of the arena

The map for the 2026 event is not yet ready and will be presented closer to the event.
Safety
Collection of children in the target area
The children must be picked up from the target area by a guardian. On the start number, there is a piece of paper that parents must tear off and take care of while the child runs. This note must be shown when the guardian is to pick up the child in the target area. This is for security reasons, so we know that the child is safely delivered to the right person.
Guardians are responsible for their own/own children in the area.
In need of health care
Norwegian People's Aid is present at the arena and can help if someone is injured or beaten. Contact the volunteers on site or directly with Norwegian People's Aid.
If it is critical, call 113.
Nursing and breastfeeding tent
In the Minipark, there is a separate changing tent with a changing mat where you can change your child or breastfeed in peace and quiet.
