Project: When effort becomes a visual love letter

On the occasion of the UTMB 2025 in Chamonix, Outside Details and Sourire Studios have partnered with On for the international campaign "Love, Ultra".

A lucid dream told through postcards printed in risography, where the boundary between reality and imagination begins to blur. A series of images designed as a love letter to trail running: between pain and beauty, between the intimate and the collective.
