Story by Joost Gremmen from Hilversum, The Netherlands, submitted on 29/07/2014
The side from the village Grone is a really tough one. In the village there are already some steep parts, but just aside the village there''s a section of 6 hairpins. The hairpins are practically flat. so you can rest for a sec, but the parts in between are at least 18%. After the hairpins it gets easier, but still it will be though (I guess around 11%). This one is a real challenge, and I understood my most people will only ride the other side.
