MIAMI -- With Tropical Storm Alberto expected to test the fleet, the Volvo Ocean Race headed from North America to Europe on Sunday.
Telefonica of Spain, skippered by London Olympic gold medal prospect Iker Martinez, led the fleet out of South Beach on Leg 7 for Lisbon, Portugal.
Alberto will test boats with 45 knots of wind and treacherous sea conditions. Several boats already have sustained major breakages during the course of the race.
Leg 7 is 3,590 nautical miles and is expected to take about 10 days.
Just 14 points separate the top four boats in the six-boat fleet.
The Volvo Ocean Race started in early November in Alicante, Spain. It will cover 39,000 nautical miles before finishing in Galway, Ireland, on July 7.
