GP Outurela is a road race held in Carnaxide, within the Oeiras area of Lisbon. It is part of the Troféu Câmara Municipal de Oeiras – Corridas das Localidades. Associação de Moradores 18 Maio organizes the event, with support from Oeiras City Council. This places it within the local neighborhood-race tradition, distinct from a standalone city marathon.
The longest listed route measures 7.38 km. Shorter options include 4.34 km, 3 km, 1.45 km, and two 0.6 km courses suitable for younger or less experienced runners. All routes are flat, with no specified climbing or descent. This straightforward course profile simplifies the event: it is a local road run offering multiple distances on a course that does not require hill management.
