The Randonnée du Lez is a mountain-bike ride in Bollène, organized around VTT routes instead of a single road-race course. The event listing is titled "RANDO," reflecting its nature: an off-road ride for mountain bikes, not an elite competition.
The listing indicates a 37th edition, marking it as a long-established local event. The event details include practical information for riders, such as sunrise, sunset, wind, rain, and temperature. It also offers a direct caution against relying solely on the forecast for a riding decision: “Who looks at the weather stays at the bistro.”
