Triatlón Ciudad de Zamora is a sprint triathlon held in Zamora, Castilla y León, Spain. Its race center is at Playa de los Pelambres, next to the River Duero. The event typically occurs in late May or early June, following the standard short-course format: a 750-meter swim, a 20-kilometer road cycling segment, and a 5.4-kilometer road run. The Zamora City Council, the Castilla y León Triathlon Federation, and Club Deportivo Triatlón Duero organize the race.
The swim consists of two 375-meter laps, the cycling portion involves four 5-kilometer road loops, and the run concludes the competition with two 2.7-kilometer laps. The course has incorporated Zamora landmarks like Puente de Piedra, with a recent bike route addition on Avenida de la Feria. As part of national and regional triathlon calendars, the race attracts skilled athletes alongside local and regional competitors. It is also promoted via the province's sustainable tourism initiative, linking the event to Zamora's riverside location instead of viewing it solely as a closed-course competition.
