Hard Enduro

Hello my name Sergio, I'm 30 years old and I live in Gradil.
I like a sport called Hard Enduro. It is a form of motorcycle riding.
It is not a sport for everybody to practicebecouse it is dangerous, and it should not be practiced alone.
I´ve left a short video on the link in order to see some of the best athletes in the world.
