The Cologne stop on the Rhine Getaway (Amsterdam → Basel) includes a bicycle tour. I am trying to find out how strenuous it is. It is listed as "demanding". I realize ability/ease are subjective. We are active senior citizens who walk & play sports daily. Haven't ridden a bicycle in a while though. What is your take on the bike tour if you have done it?
Do they cover a lot of distance?
Is the ride in short spurts with stops?
Any guidance/description you can provide is greatly appreciated.
