The Du-Cross Benavente San Isidro begins and ends on Avenida Donantes de Sangre in Benavente, within Spain's Zamora province. This cross duathlon is structured around two roles: one teammate runs while the other cycles a mountain bike. The event commences with a run, followed by the bike segment, with distances of 1.5 km, 3 km, and 13 km specified by category.
The format accommodates children, youth, and adult categories, with routes adjusted for each age group. Teams can be male, female, or mixed, emphasizing collaboration over individual performance. Now in its fifth edition, the event is still establishing its history. Local officials and organizer Oscar Gomez have included it in Benavente's San Isidro sports program.
