Semi-Marathon de Montejunto 2026

The Semi-Marathon de Montejunto is a 21.0975 km road half marathon held in Cadaval, within Portugal's Lisbon District, typically listed for early October. It is closely associated with Montejunto mountain, distinguishing it from flat city half marathons; race listings identify it as both a road race and a mountain event. The course consists of a single loop, featuring winding paths along with climbs and descents that present a technical challenge rather than a straightforward speed test. It is suitable for runners who enjoy the half-marathon distance but also seek a trail-like challenge. Cadaval is located approximately one hour by car from Lisbon, making it accessible for those incorporating the race into a broader regional trip.
