Born January 26th, 1992 and still growing up.

I live near the shores of Como Lake, in the Italian Alps, in a playground that offers a variety of surfaces and grades, from the trails to the tarmac, beautiful mountains, iconic races and nice training conditions.

Something that I have always appreciated and has allowed me to develop the #anysurfaceavailable style that I pursue. Which is running fast and moving with agility in any kind of terrain.

My goal is to become the best version of myself and to leave something worth to the sport of trail and mountain running, which means giving a better opportunity to the athletes who will come after me.
