Semi-Marathon de Castro Marim 2026

The Semi-Marathon de Castro Marim offers runners two road-race options in Portugal’s Faro District: a 10.5 km race or the full half marathon distance of 21.0975 km. Scheduled for early September, both distances are single-loop courses, avoiding repeated circuits. The event combines seaside running with sections through Castro Marim, providing a coastal Algarve character beyond just the waterfront. The route incorporates in-town streets and roads near the sea, with the 10.5 km option being the more popular choice. Post-race, the local area provides several accessible attractions: Castro Marim Castle is nearby, Monte Gordo beach is a short drive, and the Sapal de Castro Marim Nature Reserve features birdwatching and salt-marsh scenery. Tavira, approximately thirty minutes away, offers a historic town visit with old streets, Roman bridges, and seafood, while Aquashow Park is suitable for families extending their race weekend.
