Skating in Holland

I have been ice-skating in Holland last weekend. All lakes were frozen. And they organized several touring races all around. The longest is the Elfstedentocht. It is 200 hundred kilometres in Friesland. But for that one the ice was not thick enough. And you should be a member of the foundation. Last time the Elfstedentocht was skated was in 1997. That is a long time ago. This has probably to do with the global heating. Anyway I did skate 80 kilometres. And know I feel every muscle in my body. Next time I should prepare a little better and more. And do some training in advance.
