The Bielsko-Biała itself will host enduro race on mnt. Szyndzielnia. the course is not published yet.
You can expect a lot of loose rocks, the area is known for that.
As always there is criticism about the course, mainly from Poles, but I, myself, am stoked!
I'm a local (currently moved to Norway, but will be there for the racing) so AMA.
