Trail running specialist since 1999

Serge Fortini

Founder and Manager of the CORFF Group / Sports Coach.

biography

Hybrid athlete with a strong entrepreneurial spirit, I have been fully dedicated since 2010 to the CORFF Group, which I founded and manage. I have created a complete ecosystem around sport: a CrossTraining gym, the CORFF Mag media outlet, and an influencer agency.

In the field, I refuse to choose between strength, speed, and stamina. A specialist in ultra-distance and intense functional efforts, I apply the same discipline in my training as in my business. My motto? "CORFF, the expression of the body through sport." I strive to embody this by performing well both in Hyrox events and on the technical trails of the world’s greatest Ultra-Trails.
