Cross de la Rose is a mid-October running event in L'Haÿ-les-Roses, Val-de-Marne, south of Paris. L'Athlé-Club de L'Haÿ-Les-Roses organizes it in Parc de la Roseraie, with starts and finishes on the central lawn before the rose garden. The program includes 4 km, 3.2 km, 2 km, and 950 m cross-country races, plus a 4 km Fun Run held as part of Pink October.
The Fun Run is informal, with no ranking or timing, allowing walkers, casual runners, families, and supporters to participate without racing the clock. Music and small surprises are featured along the 4 km route, breast cancer information stands are available in the park, and proceeds benefit La Ligue Contre le Cancer. Bibs are collected at Parc de la Roseraie on rue Watel, registrations are handled online in advance, and the event has passed forty editions.
