The Folegandros Challenge Run is a road race on Folegandros Island, Greece, offering 21.1 km, 10 km, and 5 km distances. Held in late September, the half marathon is the primary event. Its route from Livadi to Chryssopigi and Pounta involves approximately 660 m of elevation gain, featuring the island's characteristic twists and climbs that increase the challenge beyond its apparent size.
The 10 km race begins at Punta Square, forming a loop with moderate ascents and expansive island vistas. Participants should recognize it differs from a flat urban 10K; one source indicates no aid stations and a 90-minute time limit. The Municipality of Folegandros, in collaboration with the local running community, organizes the event. The inaugural edition received commendation from Antonis Sp. Papadopoulos, who described it as one of Greece's finest routes.
