Each event indicates which forms of proof of passage the organiser will accept:

GPS track as proof of passage - more information about how to use GPS validation here.

E-brevet smartphone app - more information here.

Traditional paper receipts eg ATM or cafe/shop

Parents or Guardians with members under 18 in their household membership can enter online on their behalf. Under 18s can enter online themselves but will need to have a consent form signed by their parent/guardian. This can be sent by post, or your organiser may be happy with a scanned form sent by email - please check.
