Santander Night Run - Etapa 1 in Teresina takes place in the Brazilian state of Piaui, offering 5 km and 10 km routes. The event focuses on running after dark, where city lights and the event's atmosphere are as significant as the race distance.
The organizer characterizes the race as a blend of music, light, sweat, flow, and freedom on the course. Villa Olimpica Servico Ltda manages the event. This format appeals to runners seeking a shorter city race with a more social, high-energy atmosphere compared to a typical morning road race.
