Every day above Santiago de Chile rises to 17,800 feet the summit of a sacred mountain of the Andes, a mountain that we see every day as a backdrop of the city. We call this mountain “Cerro El Plomo”. The original native peoples of the Andes worshiped the mountains for millennia and ascended to them on a spiritual pilgrimage. Cerro El Plomo is the "Apu Wamani" of the Mapocho valley, in the Quechua language; The Guardian of the Valley. It was a sanctuary of height for the INCAS because from its glaciers came the water of the Mapocho river, main tributary of the valley for its harvests. Inner Mountain invites you to find in its ascent the harmony with a majestic natural environment and the inner journey obtained by the sacrifice and effort that implies to go to the mountains, and also carrying a bike!. El Plomo mountain is one of the longest downhills in the world, completing more than 4,000 meters unevennless of just greatness downhill, starting at 5,424 meters above sea level and ending at 1,300 m.a.s.l.. A challenge only for MTB experts. To get into this experience of climbing the great big mountain "El Plomo" by bike, you have to be very clear that this is a high mountain experience, and carrying a bike. It is an experience completely out of your comfort zone. The "Bigmountainbike" concept is a new trend that seeks to find the limits beyond the daily that we usually ride. It is to search in suffering, a joy and a unique experience that only gives you the mountain. That is why the mind and good acclimatization in height is key to achieving the success of any bigmountain bike expedition.
