Restonica Trail Blanc is a winter trail event held in the Niolu region. The start and finish are at the Popaghja forest house within the Valdu Niellu forest, located in Albertacce. Restonica Trail organizes this event, which takes place on a Sunday in February and includes chip timing. The day focuses on trail running and walking, not solely on an elite race, and it supports the Marie Do organization through fundraising.
The 8 km initiation race follows the same path as the walk, allowing newcomers and walkers to experience the mountain-forest environment alongside the runners. Online registration is encouraged, though walkers may register on-site. Participants in the races must possess an FFA license number or a PPS health attestation. Minors participating in the walk or initiation race require parental consent. The event maintains a local Niolu connection with support from Paul-André Acquaviva of the Niolu Sports Association.
