The Reims Champagne Run is an October race weekend held in Reims, located in France's Marne department within the Grand Est region. This event is the renamed version of Run in Reims, now offering road races, trail races, a relay, and children's events, moving away from a single-distance format. The race distances range from the 3 km Course des P’tits Rèmes for children up to the 87 km Sacré Trail. Included are a 5 km, the 10K de Rémus, the Semi des Rois half marathon, a 42 km Sacré Trail, and a four-person Sacré Trail relay.
The road races highlight central Reims instead of directing runners immediately out of the city. The 10 km and half marathon are FFA-certified, utilize start corrals and pacemakers, and pass notable landmarks such as the Porte de Mars, the Basilica Saint-Remi, and Notre-Dame Cathedral. The longer Sacré Trail distances introduce a more challenging nature-running aspect to the weekend. Consequently, the same event caters to children, novice 5 km participants, club runners aiming for a specific road time, relay teams, and ultra runners seeking an extensive day on the trails surrounding the Champagne region.
