The race begins with a one lap 1,500m swim from Tirantes Bridge up to approximately the middle of the Island.

Heading past the cultural centre ‘Pazo da Cultura’ to Compostela Avenue, taking the N550 to more or less the border with the town of Barro. After 2 laps (39.5 km), athletes return to transition.

They then have a few meters on foot between transition and the finish line.
