The Triatlón Villamuriel begins with a 750 m swim in Esclusa 33 on the Canal de Castilla. This short-format triathlon in Villamuriel de Cerrato, Palencia, includes a 20 km bike course and a 5 km run following the swim. Recent event listings indicate it takes place in September, and Buscametas describes it as non-competitive.
Club Triatlón Villamuriel is the organizer, and the event is included in the Circuito Diputación de Palencia. The swim in the Canal de Castilla provides a distinct local element, with the remainder of the race structured around a sprint distance suitable for both novice triathletes and club competitors. The federation's website mentions a fourth edition, suggesting it is a regular local event. Athletes registered with the FTCYL use their own timing chip, while other participants rent one during registration, which must be returned post-race or upon withdrawal.
