Below you’ll find information on the upcoming Maratón San Carlos–Guaymas and the separate Medio Maratón Guaymas.
Maratón San Carlos–Guaymas, November 8, 2026
The 16th annual Maratón San Carlos–Guaymas takes place on Sunday, November 8, 2026, bringing runners to the beautiful coastal route between San Carlos and Guaymas.
Important Update: 42km Marathon Cancelled
The organizing committee has announced that the 42km marathon distance will not take place this year. The decision was made due to insufficient registrations and safety concerns associated with providing adequate Civil Protection coverage along the additional 21km section of the marathon route.
Organizers explained that the number of registered marathon participants was also insufficient to meet the minimum requirements for competitive men’s and women’s categories.
All registered 42km participants have been notified and offered alternatives.
The 21km half marathon and 6.5km race will proceed as originally scheduled.
Celebrating Sea Turtle Conservation
This year’s event, dedicated to Abraham Mendívil Ruiz, celebrates sea turtle conservation with the theme “Sobreviviendo y Regresando al Mar” (Surviving and Returning to the Sea).
The event helps raise awareness of marine turtle protection and the work of San Carlos’ Centro de Rescate, Rehabilitación e Investigación de Fauna Silvestre (CRRIFS).
The colourful race shirts and medals feature sea turtle designs, reflecting this year’s conservation theme.
