Across Switzerland, solo

In 2025 I crossed Switzerland twice on foot, alone, no sponsors, no team — Zurich to Geneva, then Constance to Lugano. Two diagonals that draw a cross on the map, each kilometre dedicated to Spring Act and the fight against domestic violence.

The hardest part was never the body. It's convincing your head to keep going. That's what I bring to coaching: I know what it takes to keep going when it stops being fun.

The basics

I'm French and living in Zurich for 4 years. Discovered the wonderful world of running while I was a Corporate Robot in a Big 4, and the passion never left me. I decided to move on and pass my coaching certification. My approach is: it is a hobby and a hobby can be both taken seriously and be fun! So I want to transmit you this passion.

esa Running certification (Erwachsenensport Schweiz / Swiss Athletics, Magglingen) — earned.
