The Acuatlón Velá de Triana begins and ends at Seville's Puente de Triana, placing the race at a well-known river crossing. As a July aquathlon, athletes compete in a swim-and-run format, distinct from a typical road race or triathlon. The event includes Sprint and Super Sprint categories, with different fees for federated and non-federated participants. Registration opens in June via the Andalusian Triathlon Federation. Entry is capped to maintain a manageable size, with Runedia indicating a 300-person limit and OF Sport specifying separate caps for Sprint and Super Sprint divisions.
The full course details are not provided, but the official distance is homologated, and both the start and finish are at Puente de Triana. The event accommodates both licensed triathletes and non-federated competitors, particularly in the Super Sprint category. Race-day amenities include a cloakroom, post-race food or sandwiches, and awards for winners. OF Sport organizes it as the Memorial Íñigo Vallejo. Source information varies on the edition number, with one listing XI and another stating it is the fourteenth edition.
