MARSEILLE, France (Reuters) - A French couple is training in the Mediterranean to prepare for what they hope will be a record-breaking three-month relay swim across the Atlantic.

Matthieu Witvoet and Chloe Leger Witvoet plan to set off from the island of Cape Verde, off the African coast, on November 1 for a 3,800-kilometre (2,360-mile) swim to the French Caribbean island of Guadeloupe.
