Inaugurated in 1978, it links the English Channel to the French Riviera and is held in July.
Famous skippers have taken part in the race, including Loïck Peyron and the four time America's Cup winner Russell Coutts.
The race is, however, not reserved for professionals, and it also attracts amateurs and students thanks to three distinct rankings.
The race visits around ten harbours along the French coast.
The boats are transported by road (trucks) midway through the race from stages held in the Atlantic Ocean to those in the Mediterranean Sea.
