At that time I could not find the root cause. I expected a projection issue but did not (yet) fix it. This is the updated code (with more parkruns added) and also rewritten in Python.
A voronoi plot or diagram is helpful to visualise the nearest parkrun in The Netherlands.
It uses the parkruns as mentioned on the website of Roderick Hoffman and uses only the ones which are located in The Netherlands. Country border and the borders of the provices are available via the GADM project. A version with the used resultion is also copied in the data directory.
The plots look like this for Netherlands with the currently (January 2024) known parkruns:
This is the version without country border because some questions in a prakrun statistics forum arose whether the lines are correctly positioned:
