The Doñana Lentisco Trail begins and ends at the Salinas de Bonanza in Sanlúcar de Barrameda, located on Spain’s Atlantic coast near the Guadalquivir estuary. This trail race takes place in November and is organized by the Municipal Sports Board of Sanlúcar de Barrameda, offering a main distance of 22 km alongside a 10 km race on the same day.
The route crosses Doñana National Park, with the appeal lying in the protected marshland environment near Bonanza as much as the distance itself. The primary race includes a 2 hour 45 minute time limit, aid stations positioned along the course, and required checkpoints, establishing it as a structured trail event. Now in its eighth edition, the race is a well-established local competition.
