Trail des Rois Maudits is a late-September trail running event held in Les Andelys, Eure, Normandy. The races traverse the Seine Valley, including forest sections and sufficient climbing to justify the local moniker, “mountain trail in Normandy.” The event features four distances: approximately 13 km, 27 km, 41 km, and 60 km, catering to a range of participants from those seeking a short, hilly run to seasoned runners undertaking a long day with considerable elevation. The 60 km route covers about 2,500 metres of climbing, and the 41 km route includes approximately 1,700 to 1,800 metres of ascent.
