Castellón Triatlón - Supersprint 2026

The Castellón Supersprint is the shortest race at the Castellón stop of Mediterránea Triatlón, a three-city triathlon series on Spain’s Valencian coast. The Castellón event begins the series in summer and is organized by Evasión Running Castellón, with support from the Valencian Community Triathlon Federation and Castellón city council. The Supersprint format is designed for a quick race: 350 meters of swimming, 10 kilometers on the bike, and a 2.5-kilometer run. The series also offers Sprint and Olympic distances in Castellón, Valencia, and Alicante. Some athletes register for a combined challenge that includes one race in each city. The "3x3x3" setup features three cities, three distances, and the same three triathlon disciplines, with options for participants who wish to repeat a distance or advance across the series.
