The race, organized by the Barcelona City Council, now allows participants to reserve their bibs through its official website, cursadenassos.barcelona. Since 2019, the event has consistently sold out its registrations week after week.
In 2025, over 13,000 runners participated in the 10-kilometer category, and this figure is expected to be surpassed in the 2026 edition. Participants who register during July and August will be entered into prize draws for gifts from the race's sponsors.
“"I encourage all Barcelonians who enjoy running through the streets of our city not to miss this sporting celebration and to close out 2026 in the best possible way. Now is the time! Reserve your bib and see you at the B100 Cursa dels Nassos in Barcelona."
The B100 Cursa dels Nassos Barcelona is a well-established sporting event that concludes the competitive year in the Catalan capital.
