La Pisciacaise takes participants into the forest of Saint-Germain-en-Laye, located west of Paris in the Yvelines. The event is set for mid-April, offering two main running distances: 5 km and 10 km. The race is associated with Poissy and the neighboring town of Carrières-sous-Poissy.
The schedule also features a 12 km Randonnée du Petit Prince walk, which includes a challenging incline near Parc de la Charmille. Additionally, there are bike-and-run events and shorter races for children. OXYBOL manages the timing, and a dedicated app offers live GPS tracking for spectators. Partner stands are available in the race village, situated before and after the forest courses.
