Two weeks solo across France, Belgium and Netherlands on my Genesis Croix de Fer 50, mostly around Ardennes, Limburg and North Brabant.
Amazing endless forests with excellent tarmac, and plenty of mud and gravel opportunities (the Marathon Plus restricted how muddy I could get).
The route from Charleville-Meziers in France up to Namur in Belgium (EV19) is unforgettable in beauty and the smooth tarmac (segregated bike path nearly all the way).
Stormy weather several days, but there's always campsites or cheap Airbnbs to retreat in.
Above all, riding through forests all day long for two weeks, choosing to go into towns only when needed/desired made for an unforgettable trip.
