Eco Semi-Marathon de Coimbra 2026

The Eco Semi-Marathon de Coimbra is a road race held in Coimbra, Portugal, typically in mid-October. Participants can select a half marathon or a 10.5 km race, with both routes designed as single loops. This event is categorized as a nature race, appealing to runners seeking an outdoor-oriented road event rather than a track-style urban circuit. The 10.5 km distance is the more popular option, serving as a suitable choice for novice runners or those preferring a shorter race. The course structure is straightforward: a single loop for the 10.5 km and another single loop for the full 21.0975 km half marathon. The race is open to participants of all skill levels, from those aiming for a personal best to seasoned competitors. Post-race, Coimbra offers several attractions: the University of Coimbra, one of Europe's oldest universities and a UNESCO World Heritage site, the Coimbra Botanical Gardens, and Portugal dos Pequenitos, which is family-friendly. Aveiro is accessible within an hour's drive, and the Bairrada wine cellars are also recommended as a post-race destination.
