Charity and Social Impact

The Rennes Urban Trail is a major solidarity event, dedicated to supporting neuroscience research. A portion of each registration is donated to the Bretagne Atlantique Ambition Foundation. These funds directly support the Institute of Clinical Neurosciences of Rennes (INCR) in their research against neurological diseases such as Alzheimer’s, Parkinson’s, and multiple sclerosis. To date, the event has raised significant contributions for these medical causes, making every stride a step toward clinical progress.

Bib Management and Volunteers

The organization facilitates a secure bib exchange platform via Klikego, which remains open until April 10, 2026. This serves as the official hub for participants to manage their registration entries safely. The massive logistical effort is supported by a dedicated team of 900 volunteers who coordinate course safety and facilitate access to the historical buildings and private locations that make the route so unique.

Race Logistics and Media

The event maintains a strong presence across social media platforms including Instagram, Facebook, and LinkedIn, where runners can view teasers highlighting new hidden locations for the 2026 route. Participants are encouraged to consult the official FAQ for practical details regarding bag drops and staggered start waves. The official website, managed by Cognix Systems, provides real-time updates and historical archives for those wishing to review past performances or prepare for the upcoming technical challenges of the urban terrain.
