A special event organized by Réseau des Émetteurs Français will celebrate the Tour de France. Each stage of the tour will feature its own callsign. Both men’s and women’s tours will be represented July 4th through August 9th.

For over a century, the Tour de France cycling race has embodied excellence, self-improvement, and the connection between regions.
