The Engineer is a 15km singletrack trail located right over San Rafael village in Segovia, in the border with Madrid. It's at the final part of our tour and we'll make a big round to reach the Engineer proper trail head. This loop goes through three Spain's provinces, Madrid, Avila and Segovia and has some 4th category climbs. We'll climb about 900-1000mts and most of it is by technical singletrack. Right before entering The Engineer we'll go down a precious small valley and there's a 10 minute push the bike.
The Engineer itself is a narrow trail surrounded by ferns and shaded by pines that is so away enough from civilization to see literally no one... it has many technical creek crossings that will challenge your mental strength, but it will pay back for its beauty and calm.
