New cycling milestone!

All 566 (numeric) postal codes of the province of North Holland have now been crossed by bike. The last postal code was 1642 at Spierdijk; what's in a name... (spier = muscle)

The registration of the rides started in 2019 (via Strava, linked to Wielervrienden.nl). The final one was today during a ride from Enkhuizen via Hoorn to Alkmaar, at a temperature around freezing point, but with a lovely sun and a cooperative easterly wind.

The route determination and navigation of the postal code challenge was a bit more difficult than that for the Dutch municipalities (see link below), but a surprise for me was that Google Maps also indicates the route when a postal code is entered as a destination. I didn't know that.

To visit all Dutch (numeric) postal codes, there would still be a lot of touring to do: 4,067–1,936 = 2,131 postal codes are still open (There are 4,770 numbered postal codes, but 703 of them are not geographic, as for PO boxes). I will most likely pass on that challenge, but... never say never.
