Tous Pour la Vie Janzé, Ensemble contre le cancer
Tous Pour la Vie Janzé, Ensemble contre le cancer is a one-day charity sports event in Janzé, France, held in October at the Site Le Gentieg. The event focuses on cycling and walking, offering road cycling, gravel, VTT mountain biking, cyclo-cross-style riding, touring rides, and a 12 km walk, all supporting the fight against cancer.
The marked courses provide clear choices for distance and surface, with GPS tracks available. Road cyclists can select a 50 km blue route or a 70 km red route. Gravel riders have a 50 km blue route, and mountain bikers can choose a 40 km blue route. The entry fee for adults with a license is 8 euros. The event also features food and entertainment at the site, serving as both a local sports activity and a community fundraiser.
Marathon Vert Rennes School of Business
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.
Ekiden de Bretagne
Ekiden de Bretagne is a seaside road relay held in Saint-Malo, on the Breton coast of France. Teams complete the full marathon distance of 42.195 km, divided among runners in ekiden style, with the race taking place in early November.
The route follows Saint-Malo’s streets and ramparts, with the sea nearby, allowing runners to sense the Breton marine air. Its slogan is “A stride in the West!”, appropriate for a team marathon within one of Brittany’s historic walled port cities.
Semi-marathon de Ploërmel
The Semi-marathon de Ploërmel is a half marathon held in Ploërmel, Morbihan, Brittany. This road race offers participants a 21.1 km challenge through the countryside, following winding roads that connect small Breton towns and pass through open local landscapes.
The region surrounding the race provides numerous activities for visitors. The Forest of Brocéliande, Château de Josselin, Vannes, and La Trinité-sur-Mer are all accessible within an hour's drive. Local residents offer encouragement along the course, and the culinary offerings are distinctly Breton, with nearby crêperies serving galettes, crêpes, and other regional specialties post-race.
Semi Marathon De Ploermel Communaute - Ploërmel
The Semi Marathon de Ploërmel Communauté is a road half marathon held in mid-February, starting in Ploërmel, Morbihan, Brittany. The primary race is the standard 21.0975 km distance, run as a single loop, attracting close to 1,500 participants with a community focus and charitable aspect.
The course combines running between towns with sections through the Morbihan countryside, utilizing winding roads connecting small Breton villages and passing near local points of interest. It offers an endurance challenge while maintaining a local race atmosphere, with residents from Ploërmel and surrounding areas present along the route to support the runners.
Semi-marathon de Laval
The Semi-marathon de Laval takes runners through Laval, located in the Mayenne department of France’s Pays de la Loire region, typically in early March with cool, spring-like weather. Established in 1978, the event features two race options: a 21.097 km half marathon and a 6 km race suitable for less experienced runners or those preferring a shorter distance.
The half marathon route combines city streets in Laval with sections through the surrounding countryside. Runners should anticipate a challenging course rather than a quick, flat one. One participant described it as very demanding, noting three significant climbs, each over a kilometer long, and a headwind near the finish, though they also mentioned a pleasant finish within Laval. The race attracts dedicated local athletes, recreational runners, and novices, positioning itself as a key running competition in Mayenne.
Ekiden de Laval
Ekiden de Laval is a team relay race held in Laval, located in France’s Pays de la Loire region. The start and finish are situated at Cour de la Résistance by Square de Boston. The primary Ekiden covers the marathon distance of 42.195 km, divided among six runners with legs measuring 5 km, 10 km, 5 km, 10 km, 5 km, and 7.195 km. A Semi-Ekiden is also offered, spanning 21.100 km for three runners, with legs of 5 km, 10 km, and 6.100 km.
The course is designed around a 5 km loop, meaning most participants will run either one or two laps based on their position in the relay. The final runner incorporates an additional shorter section of 2.195 km. Teams can consist of friends, family, colleagues, club members, or local competitors. The event attracts notable Mayenne athletes who compete for the marathon relay victory. Refreshment stations are positioned near the Pont de l’Europe exit at Square de Boston and at the finish line. Participants are required to provide their own cups.
Semi-marathon de la vallée de l'Oust - Malestroit
The Semi-marathon de la vallée de l'Oust is a Saturday race in Malestroit, France, offering both a half marathon and a 10 km option. The half marathon begins in the early afternoon, with the 10 km starting shortly after. The field is capped tightly, and entries and bib transfers may close once the approximately thousand-runner limit is reached.
The route begins with a short section through Malestroit’s narrow streets, then follows the Nantes to Brest Canal. Runners use the greenway toward Roc-Saint-André before returning on the towpath, transitioning quickly from town lanes to canal-side running. Registration requires a valid running license or PPS, bibs are collected on site, and every participant receives a gift.
Semi-marathon de Brière - Saint-André-des-Eaux
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.
Semi-Marathon de Liffré
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.

About Marathon races in Rennes
Rennes Training Notes
Rennes hosts 16 Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.
Locals run Rennes from the centre out to green space fast. The Parc du Thabor loop is 5km and the Canal d'Ille-et-Rance route covers 7km. The Canal d'Ille-et-Rance route covers 8km, while Gayeulles Park gives locals 4km and 6km loops. K2 Running Club Rennes meets Tuesday and Thursday at 7:30 PM, and Je Cours à Rennes keeps it all-levels. Tout Rennes Court, Rennes Urban Trail, Roazhon Run, and Marathon Vert Rennes School of Business are the anchor events.
Locals ride the Vilaine valley, the Canal d'Ille-et-Rance Path, and the small countryside roads once the city centre drops away. Rennes gives riders 232 kilometres of cycle routes, plus the 104-kilometre Cycle Express Network for clean base miles. The Ronde van Roazhon starts at Mail François Mitterrand and rolls for 65km with 430m elevation gain, so it works as a proper gravel check. Gwern ar Sec'h Gravel is the anchor race. Gwern ar Sec'h Gravel covers 8km and 570m elevation, and Forêt de Paimpont puts 300km of trails 25km west.
April to September is the clean window for long rides, steady running, and stacking Z2 without overthinking kit. Summer gives Rennes 1,700 to 1,850 annual sunshine hours, so locals use mornings for intervals and evenings for relaxed spins along the Vilaine River. Parc des Gayeulles and Apigné Ponds stay useful when the centre feels full. Winter changes the rhythm more than the plan. Rennes gets less rain than western Brittany, so runners keep the canals and park loops alive, while cyclists lean on REV lines, towpaths, gravel loops, and cyclocross-style trail days.
