How do you get this special Nike background for the Apple Watch?

Hello everyone

I have now bought an Apple Watch and now I am adjusting it to suit me.

I would have a question for the background: I know that with the new update, everyone will have access to the Nike backgrounds, but where is the background that Apple has on their website? (I also put it in here below)

Does anyone know how to get this?

Thanks in advance:)

Kind regards,

Diego
