For one exclusive event in Paris, Julbo teams up with Culture Run & runpack to offer a new running challenge: an urban orienteering race, inspired by the outdoor world, in the heart of Paris’ 5th arrondissement.

As a bonus, test REACTIV photochromic technology in real conditions, during effort, while exploring Paris from a different perspective.

No phone.
No GPS.

An invitation to lift your eyes, read the city differently, and reconnect with the outdoor mindset — right in the middle of Paris.

The challenge

• 40 participants, divided into 10 teams of 4

• A route of approximately 6 km

• 6 checkpoints to find, in a specific order

• A map and a compass to navigate

• Riddles and cultural clues along the course

• No phone, no GPS

A collective, playful and immersive experience, combining running, thinking and urban exploration.

Test REACTIV technology on the run

For the race, you’ll be equipped with Julbo sunglasses featuring REACTIV photochromic lenses.
They adapt instantly to changing light conditions — from shaded areas to bright streets — for optimal visual comfort from the first to the last kilometer.
