Participants will enjoy beautiful landscapes unique to the Oliveira de Frades area, with well-marked trails and several refreshment points.

The atmosphere is both competitive and festive, with podium awards for general and age categories, including e-bike divisions. The event includes logistical support such as meal options, showers, and safety measures, making it suitable for a broad range of mountain bikers, from elites to amateurs and families interested in the ecotourism ride.
