This trail run is challenging and beautiful. It has some sections covered by trees and some open sections where the sun will be your best ally. We will start on the beach on a hard sand trail. Then we hit Playa escondida trail which is trail mostly covered by trees and good shade. This trail has a steep clim at the end. After this section we hit the road for about 1 minute before entering Monte Mapiro. Monte Mapiro starts with a long steep hill. This climb is very loose and will put to the test your shoe selection. Once you get to the top of the hill is basically rolling hills before you make the U turn. Athletes doing the 21km will do 2 full loops and the 10km will do 1 loop of the same course.
