That is truly scary.
Beautiful scenery, but don't think that I could ride a bike in those conditions.
The truth be told Canary, the ice covered road only lasted perhaps 1km. I was quite hesitant, but what can you do, you keep riding forwards till you have a viable alternative. When I reached the viable alternative, an area of flat road with a carpark, which appeared to be the top of the pass, I stopped for a few photos, obviously staying on the bike, then I could pretty well see that the road headed back down into a valley again, so I took the gamble that the ice/slush would only last as long again as I had already ridden, ie if i turned around it would be the same net result, except I'd have to ride further to reach my destination.
In fact, strangely, last time I rode in such conditions, was in muddy snowy icy slush in india, and I knew I had to ride back down it again, and I was shittin myself, but on that occasion, as happened today, i found that riding downhill was easer than uphill. Maybe because of the extra weight on the front wheel ?
