Trail des Poères is a small trail event in Marcelcave, in the Val de Somme near the edge of the Santerre area. It offers two timed trail races: 17 km with 130 m of climbing, and 8 km with 57 m of climbing. An 8 km walk is also available on the same route as the shorter race, with no timing and no rankings.
The courses are set up for local runners as well as younger entrants, with the 17 km open from junior age and the 8 km from cadet age. Both races use overall rankings and give podium awards to the first three finishers. GPX files are available for the routes, refreshment points are provided, and runners collect bibs on Sunday morning on Rue du 8 Mai beside the town hall.
