The Trail in Calvi is a Corsican trail-running event held in Calvi, located on the island's northwest coast in the Balagne region. Its routes are set between the sea and the mountains. The adult program offers three distances: Giru di A Serra (10 km with 350 m elevation gain), Giru di a Revellata (16 km with 600 m), and Capu di a Veta (29 km with 1200 m). The longest race is classified as Trail XS, presenting a significant mountain challenge without being an ultra-distance event. The Sport in Calvi association organizes the event, which also includes races for children aged 5 to 16.
The courses traverse Calvi’s coastal and hill terrain, distinct from a flat road-race format, and have attracted around 850 participants. The event's accompanying activities are extensive for a trail weekend, featuring a sponsors’ village with stands, food, refreshment points, entertainment, and an evening concert. One past edition included a fan zone at Notre-Dame de la Serra with a DJ, offering spectators views high above the town in addition to the finish line. The race also emphasizes its environmental commitments through organized trail clean-ups, nature-awareness activities involving schoolchildren and runners, and aid stations and the finish buffet designed for zero plastic waste, utilizing eco-cups and reusable or compostable containers.
