The Marathon Vert de Rennes is a 42.195 km road race in and around Rennes, Brittany, held annually since 2011. Its environmental commitment is directly tied to the race: each kilometre completed results in one tree planted, with organizers reporting over 1.3 million trees planted since the event's inception. Participants can run the main marathon individually, in pairs, or as relay teams. The event also features a 10 km race, a women-only 5 km, night races, and a family walk. The current marathon course is primarily within Rennes, following a swift, FFA-sanctioned double loop along the Ille and Vilaine canals, concluding in the city center on the Esplanade du Général de Gaulle. Previous editions commenced at Cap Malo and traversed roads through the northern Rennes Métropole communes before reaching the city. The race has hosted the French Marathon Championships, and its inaugural event was sponsored by Haile Gebrselassie. Student and corporate challenges engage teams, while pacemakers, aid stations, on-route music, plogging sessions, and galette saucisse at the village contribute to the weekend's local character beyond the marathon itself.

The Semi-marathon de Brière is a March half marathon held in Saint-André-des-Eaux, Loire-Atlantique, organized by Esco 44 Saint-André-des-Eaux. The 21.1 km main race qualifies for the French Championships, attracting runners aiming for standards and locals seeking a flat, green run. Demand can be high; the solo field is capped at about 2,200, and one anniversary edition sold out twelve minutes after registration opened. The course is primarily road (70% paved, 30% stabilized paths), forming a loop through marshes, forests, and hamlets near Brière. Pace setters typically target 1h30, 1h45, and 2h00, with aid stations on the course and a larger one at the finish. The event includes more than just the half marathon: a short popular race, Nordic walking, children’s races, joëlettes, and adapted sports offer participation for a wider group than just club runners.

The Semi-Marathon de Liffré is a 21.0975 km road race held in Liffré, a town in Ille-et-Vilaine, Brittany, near Rennes. Typically run in early April, the half marathon begins in the morning and is open to runners from the junior category upwards. The event also features races for children and juniors, catering to a range of age groups. It holds a national FFA label and qualifies participants for the French Championship, lending a competitive atmosphere to the local event. The course is designed for speed, consisting of two identical road loops with a downhill start and a finish on Rue Jules Ferry in central Liffré. Runners navigate the town center, rural roads, and the Rennes forest, with aid stations provided every 5 km. The race encourages fast times, evidenced by course records of 1:04:12 for men (Paul Njoroge Mugo) and 1:13:11 for women (Dorine Murkomen), with a cash bonus offered for any new record. While beginners are welcome, the flat, rolling course also attracts athletes aiming for personal bests or championship qualification.
