Randonnée Pierre Lina is a one-day road cycling randonnée held in Marly-le-Roi, located in the Yvelines department west of Paris. Participants gather at the Gymnase du Chenil for sign-on, which runs from 7:45 to 9:30 in the morning. The event is organized by Club Cyclo Tourisme de Marly. The entry fee is modest, with distinct prices for the general public and club members.
The ride provides three road route choices: a 50 km route with 500 m of elevation gain, a 70 km route with 700 m, and a 90 km route with 875 m. The 50 km and 70 km routes are designated as blue level, while the 90 km route is rated red. This setup accommodates both consistent club riders and individuals seeking a more challenging local excursion. While listed alongside road cycling and cyclosportive events, the format aligns more closely with a local club randonnée than a closed-course race.
