ISLAMORADA, FLA. (WSVN) - Hundreds of participants competed in waters off the Florida Keys for an annual open-water challenge in the Atlantic Ocean.

Saturday’s Swim for Alligator Lighthouse event initially started as a way to raise awareness to preserve the nearly 150-year-old Alligator Reef Lighthouse and five other aging lighthouses off the Keys.

Four hundred and sixty U.S. and international competitors took part in the challenge.

Thirty-year-old Michael Schultz from St. Pete Beach, Florida, emerged as the top individual swimmer.

Proceeds help fund college scholarships for Keys students interested in competitive swimming.
