The Naoussa Vermio Trail is a mountain-running race series held in Naoussa, a town situated at the base of Mount Vermio in northern Greece. The event takes place over a weekend in September and is organized by A.S. Naoussa Vermio Trail in cooperation with the Municipality of the Heroic City of Naoussa.
The courses begin and end in the Agios Nikolaos grove, a familiar green space on the outskirts of Naoussa. The Arapitsa River originates in this same grove, linking the race directly to a primary natural feature of the town and the slopes of Vermio.
