The Run & Bike d'Alençon begins in Saint-Rigomer-des-Bois, a short distance from Alençon, leading competitors into the Sarthe forests in March. This event involves alternating between running and cycling, rather than completing a single discipline throughout. The available race distances are 9 km and 18 km, positioning it as a brief off-road challenge rather than an extended endurance event.
The route crosses the Perseigne forest, offering a woodland environment near the town but separate from urban roads. ALENÇON TRIATHLON is the organizing body. The second edition introduced longer distances and an additional race category. Previous XXS Jeunes, XS, and S formats are noted as either discontinued or awaiting rescheduling, indicating the event's program is still developing.
