Trail André d'Ormesson

On March 21, 2027, runners and hikers will converge on the picturesque Château d’Ormesson-sur-Marne for an unforgettable day of trail running and walking. The eighth edition of this beloved race offers three distinct courses through some of the region's most stunning natural landscapes: a challenging 21km run with over 400 meters of elevation gain, a timed 20km march also featuring 420m D+, and an accessible 10km walk that includes 175m in elevation.
The event kicks off at the historic Château d’Ormesson itself, nestled within the lush Forêt Domaniale de Notre-Dame and surrounding parklands of Ormesson-sur-Marne. Participants will traverse a mix of woodland trails and scenic paths, immersing themselves in nature while exploring this richly forested area.
For those who complete the 21km trail run, there is an opportunity to join the SOM Challenge by participating in at least three qualifying races across various events such as the Sagittaire de Sucy or Noctambule de Marolles. The shorter 10km course also counts towards the ORPI 94 challenge.
This event celebrates a unique blend of environmental stewardship, athletic competition, and cultural heritage, making it an ideal day out for both seasoned athletes and casual enthusiasts alike.
