TriRelay is a team relay race series held in Pineda de Mar, on the Barcelona coast in Catalonia. Its main event is a Super Sprint triathlon, structured as three short triathlons connected sequentially. Teams send out relay members in order, with the clock starting at the first athlete's departure and stopping upon the final teammate's completion. The triathlon course consists of a 300 m swim, 7 km of road cycling, and 2 km of road running, with racing taking place along the seaside, sand, and city streets.
The series also offers duathlon formats, where each of the three teammates completes a full Super Sprint duathlon before passing to the next participant. Additional options include XS triathlon or duathlon distances, a Duathlon TOP distance, and a popular duathlon for athletes preferring the run-bike-run format without swimming. A recent addition, the TriRelay Hyatló format, introduces a hybrid race combining running with functional workout stations, coinciding with Hyatló's introduction as a new specialty in Spanish triathlon. Club Team TriRelay organizes the event, emphasizing team pacing and smooth transitions over individual performance.
