Course
The Trail de Fontainebleau is an iconic 45-kilometer race with 800 meters of elevation gain, taking place in the heart of one of Europe's most celebrated forests. Located just sixty kilometers south of Paris, the Fontainebleau forest spans over 25,000 hectares and provides an exceptional playground for local trail runners and international athletes visiting the French capital alike.
The course winds through the varied landscapes that have earned this forest massif its worldwide fame. Runners navigate between sandstone boulder fields — spectacular rock formations shaped by millions of years of erosion — that have made Fontainebleau the world capital of bouldering. Technical trails cross the platières, sandstone plateaus covered with fine sand, before plunging into shaded valleys carpeted with ferns and heather. The diversity of tree species — centuries-old oaks, majestic beeches, Scots pines, and birches — offers an ever-changing forest spectacle through the seasons.
The elevation gain, modest in appearance at 800 meters of D+, proves deceptively challenging due to its repetitive nature. The short but relentless climbs and descents, often on sandy or rocky terrain, intensely work the stabilizer muscles and demand constant vigilance. Passages over sandstone rocks, sometimes slippery, require sure-footed technique and unwavering concentration. This is a trail that rewards endurance and agility far more than raw climbing power.
Fontainebleau is inseparable from the history of France. The royal château, residence of French sovereigns from Francis I to Napoleon III, dominates the town and reminds visitors that this forest served as a royal hunting ground for centuries. Runners tread paths steeped in history, passing near the Franchard gorges, the Fairy Pond, and the Elephant Rock — sites that have nourished the collective imagination for generations. Its proximity to Paris also makes it a particularly accessible event for international runners.
For trail runners visiting from abroad, the Trail de Fontainebleau represents a unique opportunity to combine a quality sporting experience with the discovery of exceptional natural and cultural heritage. Logistics are simplified by excellent rail connections from Paris, and the town of Fontainebleau offers all the amenities needed for a comfortable stay. Whether you are an experienced runner seeking demanding technical training or a nature enthusiast wishing to discover the hidden treasures of the Île-de-France region, this race will meet and exceed all expectations.
