Alternatively, the course can be split into five shorter sections, such as Mayenne to Montflours and Montflours to La Pignière. Mandatory equipment is required, and aid stations are cup-free. The inaugural event attracted 550 participants. Organizer Le Son de vie allocates profits to Deux rayons de soleil, supporting twins with cerebral palsy, and to the departmental Handisport committee.

The routes traverse varied trails through Breton nature, emphasizing off-road running over a flat city course.

About Half Marathon races in Rennes
Rennes Training Notes
Rennes hosts 14 Half 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.
