Every time there is snow I get out for training in parkings and roads !!!
I live in Zurich you see and we have snow quite oftenly.
I saw these training sessions but I am not sure the 290CHF is worth it for me.
Only this season I have something like... 8 hours of pure snow drifting and I quite good now.
Do you live in Switzerland ?
PS : this morning for example, we had snow, yesterday as well
