10. What license do I need to participate?

To participate in a triathlon in the TRI HARD Series, you need one of the following licenses:

• NTB trial license (This introductory membership is valid for a maximum of one calendar year)
• NTB athlete license
• KNWU competition license
• KNAU competition license
• KNZB competition license
• Competition license from a foreign triathlon association.

PLEASE NOTE! A basic NTB membership is NOT sufficient to participate in a competition.

If you do not have a license from the list above, you will pay an additional fee for a day license upon registration.
