Endurance swimmer forced to end record quest

A 49-year-old grandmother and veteran endurance swimmer had to give up on her quest yesterday to become the first woman to swim unaided from Cuba to the Florida Keys, unable to close the gap on the last 26 miles of a more than 100-mile ocean odyssey.

Penny Palfrey had fended off painful jellyfish stings while keeping an eye on hammerhead sharks as she attempted the crossing without a shark cage. But her support team said the tricky currents of the Florida Straits proved to be her biggest obstacle, thwarting her achingly close to her goal.

All told, the British-born Australian athlete had been swimming nearly 41 hours since plunging into balmy waters near Havana, Cuba, on Friday to start out. She was about three-quarters of the way into her swim when she gave up the effort, just 26 miles south of Florida’s Key West.
