We follow the coastline that lies on the Ordnance Datum. This coastline runs roughly from Groningen to Goes. Without human measures such as building dykes and pumping, this would be the coastline in the Netherlands. 

We use the coastline as a metaphor because it makes clear that climate change can have a real impact and that it could affect everyone in the Netherlands. As a country with a quarter of its surface area below sea level (NAP), we are vulnerable to flooding. 

At the same time, our bicycle tour shows that with cooperation, speed and perseverance, we can achieve a great deal. The same aspects play a role in tackling climate change. Only together can we prevent the NAP coastline from becoming a reality.

The route is not signposted. We trust that all participants can get by with a garmin or gpx reader. The exact routes will be announced a week before the ride.

At the break locations there will be simple technical support: So make sure your bike, and yourself, are in top condition!

* Information on sea level rise from KNMI can be found here.

The routes

The routes will be final a week before the tour and will be made available to participants as GPX or TCX files. A first impression of the routes can be found below. The routes differ from the 2022 routes.
