Cycled from Amsterdam to Rotterdam today. This is a route that I first tried in 2017, in reverse. I failed miserably back then, not in shape enough and not used to the Dutch winds, so I had to take a train back from Gouda 😅 Today it worked out quite smoothly (sans a couple wrong turns that were quickly corrected). 80Km in total and I could probably do some more after lunch.
Also, the cyclists union route planner (https://routeplanner.fietsersbond.nl/en) is a great website!
