Olympic duet synchronized swimming, Gemma Mengual and Ona Carbonell , were encouraged to overcome the challenge proposed them by Actimel to perform a choreography in the sea. Every year hundreds of bathers are concentrated in the beach of Sant Sebastià in Barcelona to celebrate the new year with a dip. We were with them in the High Performance Centre of Sant Cugat preparing the choreography and then enjoying his performance on the beach of Barceloneta. An army of enthusiastic bathers shelted us in that frosty morning. They were, as always, unstoppable.
