This event commemorates the twinning between Saint Barts and the Swedish town of Piteå, as well as the long-standing ties between the two territories. At the heart of the event are several activities, including the "Gustavialoppet" race and the "Foulée des Ti Mouns". This sporting contest offers both adults and children the chance to take part in a thrilling race. For those who prefer a more leisurely approach, a walk is also on the program.
