Inflection point

In February 2012, after reflecting on the future of the Club, on our personal, professional and family concerns, we established the basis of what is now the Radikal Swim Club: a meeting point, a space for sharing experiences, a dynamizer of the open water movement and finally a center of innovation and constant improvement of everything related to open water swimming.
