The Semi-Marathon de Xéres is a 21.0975 km road half marathon held in Jerez de la Frontera, located in the province of Cadiz, Andalusia, Spain. It takes place in late October, and the event uses the French name Xéres for Jerez, the city where runners begin.
The course consists of a single loop through Jerez, incorporating city streets, public parks, monuments, and a section along the coast. It is part of a larger series of races, but the specific details indicate it is primarily a standard road half marathon focused on Jerez, not an event with multiple distances.
