Following the success of the previous edition, where the Huelva San Silvestre became the second most attended race in Andalusia, the organization is now focused on enhancing the runner's experience and strengthening its social and environmental impact. This popular and non-homologated competitive circuit seeks to transform the city's streets into an accessible, dynamic, and committed sports meeting point.

For this edition, the organization has prioritized service quality, expanded incentives for participants, and encouraged greater citizen involvement. A fundamental pillar of the Onupolis 2026 Circuit is sustainability, with measures designed to reduce the environmental footprint of the events, including emission control, noise pollution reduction, and more efficient management of waste generated during the events.

The solidarity component will also play a prominent role, with the Women's Race maintaining its charitable nature in favor of the Huelva Association for Breast Cancer (AOCAM). This reinforces the connection between sport, awareness, and support for women affected by this disease in the province of Huelva.

The collaboration between the Huelva City Council, with mayor Pilar Miranda and the Councilor for Sports, Health, and Consumption María de la O Rubio, and the promoting company Consulting TPO, led by Vanessa Arana, is crucial. This support is complemented by sponsors such as Huelva Deporte, Toyota Huelva, and GTA, among other collaborators.

The event calendar includes seven dates throughout the year, held in emblematic city locations such as Parque Zafra, Parque Moret, and Casa Colón. Registrations are already open through the circuit's official website. The circuit maintains its inclusive nature with distances of 2, 5, and 10 kilometers, adapted to different runner profiles. Registration fees remain between 3 and 13 euros, with discounts for those who complete all races, and participants will have access to promotions, raffles, and exclusive content.
