La Jarosa- Cerro de Salamanca tour

UNfortunately I could not leave early to go with the bike club on their trip to the Segovia side of the Sierra de Guadarrama. Instead I took the bike in the car to La Jarosa at midday to climb up to Cerro de la Salamanca and do the path we climbed on Wednesday in reverse. Hot day, 40 in the sun, but with some breeze. Got lost in the woods near the reservoir, but found the road I descended a couple of years ago and climbed to the Camino de Mines on steep exposed forest road. 1:05hr. 'Marco's' website of Tiraleras de Madrid says that there are two 5* techncal descents near here - the Cerro de la Salamanca, and Cerro de Cueva Valiente (he has a little map). Dropped down to the start of the climb to Cueva Valiente (1903m), but it is a 2.3k carry of the bike - could'nt be bothered, so climbed back to the road, and up the path to the Refugio. Marco reckons he can do it without putting a foot down - but a long boulder strewn path is still beyond me. Fantastic descent of stones and rocks to the col, (collado) and then down in the La Jarosa valley on the same technical path as last week. Followed the road north instead of south, passing two lost bikers whom I pointed in the right direction. Took a sort of twin path to the one on the other side of the valley down through the firebreak. At the end there was a very steep and loose earthed gulley to slide down followed by a travesing path. One surprise jump on the road and a final climb back to the car. 29k, 3:50, 870m.
