This urban trail orientation course follows the GR75. Starting at La Villette, tour the capital, discovering Paris anew. Navigate marker after marker, guided by white and red signs and hidden clues to scan. The route winds through nature trails and forests surrounding the city, including the Bois de Vincennes, Bois de Boulogne, greenways, Montmartre, and up to the Sacré-Cœur, plus many lesser-known parks. Go solo, in a relay, or as a duo, and transform your run into an exploration.
