OEIRAS

THE HEART OF THE MARGINAL.

A waterfront city linking Cascais and Lisboa — and the starting point of the 10K.

OEIRAS

The heart of the Marginal.

Waterfront promenades, forts, marinas and the starting point of the Marginal 10K.

10K Start

Santo Amaro

The 10K begins at Praia de Santo Amaro and heads east towards Lisboa.

Waterfront

Run beside the water

Oeiras is where the race fully embraces the coastal character of the Marginal, with long waterfront sections and open views.

Between cities

The connecting point

Oeiras links Cascais and Lisboa and gives the event its central coastal identity.

RACE EXPERIENCE

Two races, one coastline.

Half Marathon runners pass through Oeiras on their journey from Cascais, while 10K runners begin their own race here and share the same finish in Belém.
