Semi-marathon de Laval 2027

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.
