Troyes is shaped like a champagne cork, and the Semi-marathon de Troyes utilizes this compact old-city setting for its May road race. The event offers a half marathon, a 3x7 km company relay, a 10 km race, and a 1 km children's race for ages 7 to 11. The half marathon course is designed for steady pacing, featuring official pacers, well-stocked aid stations, refreshing water features, and a flat, fast route with no significant climbs, as noted by the organizers.
The course winds through the historic center of Troyes, following the Seine quays and passing the Saint-Pierre-et-Saint-Paul Cathedral. Participants will run by medieval half-timbered houses, cobblestone streets, the Jardin des Innocents, and the Parc des Moulins. This route appeals to both runners aiming for a personal best and those wishing to explore the city on foot. The event accommodates company teams, 10 km runners, children, club athletes, and first-time participants, with support along the route and a festive finish.
