The best and biggest race in the Netherlands will take place on April 19th 2025. It's also called the innofficial 6th monument, starts in Maastricht, goes through the beautiful hilly countryside of South-Limburg and ends in Valkenburg 🧡. The course isn't published yet, but according to rumors it will be similar to last year's course with about 156 km and 1700 meters of elevation and the finishline behind the top of the Cauberg. Last year's edition was won by Marianne Voss who profited from an early celebration by Lorena Wiebes.
If you have any questions regarding the quite complicated course or the roads, feel free to ask. (A lot of my outside training takes place on these roads, so I know them pretty well to say at least.)
