Fortunately a mile down from my makeshift campsite there was a bridge bicyclists can cross river to get on the other side of the river and continue down the path. Can tell how good the path is by all of the people of all ages out there with two panniers bags full and some with sleeping bags. Electric bikes are heavily used. It seems that 90% of the trail is flat. The one thing that make me uncomfortable is on the narrower roads there is not a lot of room for cars to pass you.
It is nice that the campgrounds are about 15 Euros a night. For bike tenters they basically just set off some land with few amenities which is what bikers need
