I'll be audaxing in Denmark, Belgium and Holland next year.
As well as at least one ride in France.
Any rides you can recommend for lazy fixed wheel flatlanders? Must be easily accessible by public transport....
March:
sa 19 200 Niederrhein D
su 20 200 Maastricht NL
You can do two 200s in one trip. Niederrhein starts in Wankum, which is about 3 hours by train from Maastricht (faster by car since it's a rather complicated rail journey). Nierrhein has a flat course arond Eindhoven with an optional stop in America to eat french fries.
I don't know how you are travelling then. The Wankum start is about 12km from the Venlo railway station, and Venlo-Maastricht is about an hour. (So I'd say it's about 1h40m)
There is talk the start location will not be in Wankum, but in Geldern, and that will make the travel to Maastricht considerably longer.
From what I heard the Wankum 400 will go to the Ardennes, and not north as this year.
The Wankum 600 is the lumpiest ride I know(I haven't done any rides in the UK except LEL, fyi), I failed it twice now. So it's on my wishlist for next year, but I'm not sure yet if it fits in my schedule, since there is a need to finish a 600 to be allowed to some ride starting in Paris in August.
My own 300 crosses the Leuven course twice but enters deeper into the Ardennes, calling at Bastogne and Huy. It'll be a real challenge for someone on fixed, a large part of the middle section is through endless forests around 500m of altitude.
And you're not even including the Mur de Huy!
Arvid has more knowledge on the flatter northern rides so he can give some good advice here.
From what it looks Zwolle didn't change the 200 and 300. Both are flat by British standards, and the organizer is even trying to put hills in them.
The 200 goes into the "hilly" Veluwe area, the big foresty area in the middle of NL, and ends with the dyke from Deventer to Zwolle, on the westside. It's a nice ride. The literal translation of "Bossen, Bulten en 'n Diek" is "Forests, Bumps and a Dyke".
The 300 is the same area as the bit that was at the end of the first round in the 1200(not the same route though), from Germany to Zwolle. I think there are about 5 hills, and the highest is in Germany at 150m or so. The organizer rides a velomobile himself, so all the hills/bumps are quite gentle.
I haven't ridden the 400 or 600 in Zwolle. 400 says "Drenthe" so I guess that's pancake flat. The 600 goes to the Sauerland(up to 500m elevation), so there is some serious elevation there. It's off in the same direction as the 300, but 300km onwards.
Zwolle is one of the bigger train hubs in NL, so very reachable by public transport.
From the rides in Lohne, Germany, I only know the 400 from 2009. I asked about the routes from the 200 and 300 last year, and they went to NL, so expect pancakeflatness. The 400 went to the Sauerland, mostly using larger roads to get there.
Zoetermeer is also easily reached by train. I haven't done any rides there.
Ossendrecht is harder, I did a 400 in 2009 there, and I rode 22km from the Roosendaal railway station to the start. The 400 went to the Ardennes as well, and includes the Mur de Huy. There is quite a long flat bit to get to the Ardennes though, and back as well of course.
