The Cursa Diagonal DiR - Guàrdia Urbana is a Barcelona road race held in May on a homologated, all-asphalt course. Starting at Avinguda Diagonal near the Palau Reial de Pedralbes and concluding at Passeig Garcia Faria, the route crosses one of the city’s main avenues, heading from Barcelona’s upper district toward the seafront. The race is chip-timed, limited to 12,000 participants, and offers a 1 hour 30 minute time limit.
The event, organized by Clubs DiR, features eight categories, a wheelchair division, and a children’s race, extending its scope beyond a typical adult road race. Participants receive aid at two liquid stations along the course, access to cloakroom service, a finisher diploma, and awards for the winners. A portion of the proceeds supports a charitable cause, contributing to the event's identity. Runner feedback highlights effective organization and a positive atmosphere, with some noting it as a day conducive to personal bests.
