Trail Des Boobs - Morsain is a local charity trail event held in Morsain, Aisne, northern France. The race features a 11.5 km discovery trail with approximately 200 metres of elevation gain. It begins in the morning and is designed for runners seeking an accessible off-road course, rather than a demanding mountain race.
The event also includes a walking option and a meal, welcoming non-runners. Morsain en Bringue organizes it alongside Roses des Dames. The event is named “Morsain en Rose” to connect the community gathering with breast cancer awareness. Now in its second edition, the modest entry fee reflects the local, cause-driven nature of the event.
