After a few steps with the swiss guys \ HELLO <_BIKE> WORLD! and the frenchman Mimille we reached the most remote area of â€‹â€‹Afghanistan: a strip of 20 kilometers wide between Tajikistan and Pakistan, and in which it seems to me the French army was at war there is no long time. This road was very pretty because of the presence to 20 kilometers of us of high mountains with summits at more than 7000 meters of altitude acting as border between Afghanistan and Pakistan. The Pamir River, a tributary of the Wahkan, which separates Tajikistan from Afghanistan, became increasingly narrow as the climb progressed and at the end we could have crossed it on foot. Finally after 12 days (for me) to go up the river bottom valley along the Afghan border we left the river and crossed the Khargush Pass at 4344 meters above sea level. On the other side we have joined the M41 road, or Pamir Highway, the main road of the country but with almost zero traffic, and which crosses the highlands and passes various passes at more than 4000 meters above sea level. It is an asphalt road, bad quality but for us it was a big change and an important gain of comfort and speed after the previous roads. We put a few pressure bars in the tires and with a good wind in the back, we flew on this road. The Pamir Highway is probably the busiest road in the world by bicycle travelers. Like the Eurovelo 6 in Europe, the Carretera Austral in South America, or the Pacific coast in North America, it is a bagged cyclist's highway. Some come just a few weeks for their holidays, mainly from Europe and Russia, but there are also many long-distance travelers because the road is the shortest route between Europe and Asia, and its reputation for its landscapes, its difficulty and the absence of motorized traffic makes it a place of passage for all travelers of my species. The landscapes were indeed very spectacular, it was grandiose, and the days were embellished by the joys of group life. One day we saw arrive in the opposite direction Eric and Robin, left Murghab, city they reached by taxi after a mechanical breakage on Robin's trike (the small complex part that fixes the derailleur to the frame was broken in after a shock, more info here, in french). A metalworker in Murghab has achieved the feat of making exactly the same piece with a piece of metal, a blowtorch and a circular saw. It is thus together that we reached Murghab, after a bivouac at 4200 meters of altitude under a magnificent starry sky. We made a detour via a stony path to go to the site of the power station that fed until last winter this very isolated town of 6000 inhabitants located at 3700 meters above sea level. The city, which contains an airport and a hospital, has been without electricity for 6 months. The \ HELLO <_BIKE> WORLD !, all three newly graduated environmental engineers, wanted to know more. Luckily, a tajik representative from an electric company came to the scene 30 minutes after we arrived while we were exploring the premises. He opened the doors to us and answered the most technical questions, told the story of the plant, the reasons for its closure and the projects to come (article detailed here, in french ). It was a privilege to be there at that time and to be able to freely explore a hydroelectric power station - without a dam, the current of the river being shortened and accelerated enough - 1.2 MW closed recently. In order to adapt to the lack of electricity, the richest inhabitants and the most luxurious hotels of the city have been equipped with gasoline generators but most of the inhabitants are now without electricity. Winter will be long for them because the opening of a new plant is not planned before a good year. We left Murghab with a lot of images in the head, that of the market in which the traders sell their products in old containers for boats, those of the rush to electric power strips when the hostel where we lived opened the electricity from 8pm to midnight, that of Samira, nice manager of a guesthouse with which we had sympathized, that of the scrap dealer to whom we went to visit, those of the abandoned power plant, huge rotors 600MW of power and hat traditional Kyrgyz residents, knitted sweaters of children's wool or the water of the heated shower over a wood fire. Past this singular and very amazing city came the most difficult part of the Pamir with new passes at 4650, 4250 and 4350 meters above sea level. It was with a difficult breath that we crossed all these passes, because of the lack of oxygen that was felt especially by drinking (we are quickly out of breath after drinking a sip of water) and the night it became more difficult to have a good sleep. At the top of a pass we doubled Tarus, a French cyclist traveling here for a few weeks. He then accompanied us along beautiful Lake Karakul and in the two new passes that followed. Finally after a week spent at 4000 meters altitude I crossed the last pass at high speed to find air and colder temperatures on the other side to the Kyrgyz border.
