Peter, I'm not really a beer person (although I do enjoy having one every now and then), but the more I think about it, the more I think that pottering about in Wallonia makes quite a bit of sense, not only for the hills but also for the abundance of unpaved paths. Out of curiosity, are you based in the Netherlands? Any chance that there are hilly bits relatively close to the Belgian border? Or, is that like asking if your cat can do maths?
hi shredder, yes I'm in the NL. most hilly bits are around Maastricht/Valkenburg/Heerlen - indeed close to the Belgian border but again the Wallon part - it's the region of the NL classic: Amstel Gold Race. they're all very short though...
