Sierra de Gredos is a mountain range part of Spain central Mountain System. It's formed by immense granitic massifs that crown all the peaks. We made a 42km-1800m climbing Enduro tour that took us 10 hours it it was all worth it. It was a total radical all mountain experience that moved our limits way beyond and pay back with an amazing descent at the end with more than 40 switchbacks and a long flow singletrack. As we hiked our bikes on top of the trail seeking for the singletrack a group of Ibex stared at us, we were in the middle of nowhere, right as we like it.
