Real demanding. Steep throughout, with no flat sections in between. And at the end it climbs even steeper. Take the challenge seriously and don't do it without enough drinking water, you'll need it! Going down is not so great. Not only are you constantly braking, but because of the many transverse grooves for rainwater, it can also be really dangerous, as some of them are deep and have hard edges. So: before you go down, you should first go up and take a closer look at the road, ok?
