B100 Cursa dels Nassos 2025 heads toward a historic, sold-out edition

Barcelona is preparing to bid farewell to the year with one of its most emblematic sporting traditions: the B100 Cursa dels Nassos, a race that, more than a month before its celebration, is already moving steadily toward a new participation record.

The excellent registration pace places the event on track to surpass all historical figures, both in total entrants and registration speed. The organization expects to sell out once it reaches 13,000 runners, the limit set to guarantee event quality and safety, surpassing the 12,000 participants of the previous edition.

The B100 Cursa dels Nassos, which this year will feature B100 The Healthy Banking, ABANCA’s digital banking brand, as its main sponsor, preserves its essence: a festive, popular and accessible atmosphere where thousands find a unique way to close the year by running through the streets of a city fully committed to the event.

Barcelona will once again provide the perfect setting for participants and spectators to enjoy a sporting and social experience that goes far beyond competition.

Organized by La Sansi together with the Barcelona City Council, the race aims to deliver in 2025 the best edition in its history, consolidating itself as one of the unmissable events on the international athletics calendar.

As tradition dictates, the day will begin with the international 5 km elite race, featuring one of the fastest circuits in the world, as evidenced by its four world records, three of which still stand.

This year, the organization hopes several records may fall. In the coming weeks, the full list of participating athletes will be announced, gathering some of the most prominent names in the international scene.
