Courses des 4 saisons d'automne - Amiens is a trail race series in Amiens, in the Somme area of Hauts-de-France. It is the autumn finale of the local “4 saisons” races, with the next running set for early November. Runners can choose either 5 km or 10 km, suitable for a short trail outing or a longer effort.
The 10 km is the more popular option, with over 300 runners in the previous edition, while the 5 km had over 100. Both distances are listed as trail races. The format is straightforward: two off-road distances, one autumn race day, and a field large enough to feel like a proper local running event.
