The Restonica Trail is a 67 km mountain trail race starting in Corte, Haute-Corse, Corsica. Runners depart at 4:30 AM, indicating the challenge: the route includes 3,900 meters of elevation gain, and competitors have up to 19 hours to complete it.
The available race details are limited, but the format is evident: this is a long, steep trail run, distinct from a road ultramarathon or a short mountain race. Kikourou lists 23 runner reports and one video for the event, providing some first-hand accounts from past participants.
