The third edition of the DiR-Guàrdia Urbana race will take place in the Avinguda Diagonal, in Barcelona, on May 31st. Participants will run 10km of the entire Diagonal, with two messages: “for you maybe is just a race, but for them is their life” and “run and help us to investigate for children with cancer”. Part of the funds collected in the race will be donated to the Translational Research in Child Cancer group at Vall d’Hebron Institute of Research (VHIR). The race will start at 8.30 AM at Palau Reial and the finish line will be located at Passeig Garcia Faria. Registrations are already open on "http://www.dir.cat/cursa-barcelona/" www.dir.cat and in any of the gyms of the group. The mission of the Translational Research in Child Cancer group is to improve the diagnosis and treatments available for these diseases.
