About this race
Trail des 7 mares is a short trail race in Gonfreville-l'Orcher, Seine-Maritime, offering two distances: approximately 12.5 km or 25.8 km. Both races are scheduled to start at 09:00, and the event is organized by la boussole gonfrevillaise.
The shorter course involves about 127 meters of elevation gain, while the longer course has approximately 345 meters. This suggests it is more of a local off-road challenge than a flat road race. One race report mentioned runners starting in the rain, with the ground conditions made more difficult by preceding wet weather; finish times for the long course ranged from just over 2 hours 19 minutes to nearly 3 hours 49 minutes.
