Hello;
I did Holland / Belgium in 2000 and it was like cycling heaven to me, it was AWESOME. Some of the cycling pathways were as wide as the highways here. We started in Harlem and rode around for 3 weeks to return to Harlem.The only hill we encountered was in Arhem.
At some "traffic circles" the cyclists have their own pathway around and they have the right of way over all traffic in the circle. Watch out for "wild roosters" (the name given to metal gratings to keep cattle and hoofed animals off the pathways).
I hope to do it (Holland/Belgium) again in 2004 and also visit Normandy as well.
