Since 2007, La Sansi has been dedicated to promoting and organizing events, managing 17 races, both popular and international, with nearly 55.000 registered participants per year. We also organize specific races or training sessions for companies and congresses.
For 12 years, La Sansi has managed the technical direction of the Mercè Bimbo Race in Barcelona (14.500 participants), donating more than €70,000 to charity. Since 2013, we have also organized the B100 Cursa dels Nassos in Barcelona (on December 31, it is expected to sell out again, with more than 13.000 bibs), where in the last three editions four world records have been broken in both the men's and women's categories—still in force—along with a European men’s record.
In 2024, La Sansi created the European project HOST4ALL. It was one of the four European organizations—and the only Spanish one—awarded by the European Commission for carrying out a project focused on adapted, safe, and sustainable sport for sporting events at the European level.
In January 2024, the World Athletics (International Federation) ranking was released, and the B100 Cursa dels Nassos was recognized as the best women’s race in the world that year, among more than 300 international races on the official calendar.
In 2020, in the midst of the pandemic, we organized several events such as the Lloretrail (the first race to present a Covid-19 prevention plan and the first authorized by the Federation), which in 2023 became the Spanish Championship, and the 42nd Cursa de la Mercè, the race with the highest participation during the pandemic with 1.500 runners. Of the only three San Silvestre races held in Spain in 2020, La Sansi organized two of them—the Sant Silvestre del Masnou and the Cursa dels Nassos—which were the most participatory.
The 2021 Cursa de la Mercè, with 6,000 bibs sold out, was the first major race in Spain during the pandemic.
In 2022, we organized the 40th anniversary race of TV3, and together with Atresmedia, we managed the Ponle Freno Badalona race (more than 3,000 bibs sold out).
For December 2025, in the four races we will organize, we expect nearly 23.000 registered participants: the Sansi Viladecans on 07/12, the Cursa Pare Noel on 21/12, the 46th Sant Silvestre del Masnou on 26/12, and the B100 Cursa dels Nassos.
La Sansi has a database with emails from more than 50.000 athletes, as well as dedicated social media channels for each race.
