Registration is open for the 12th Annual race across the islands of the Florida Keys in this Southernmost part of the United States.  The Keys is a chain of unique and inter-connected islands--some inhabited, some not--ending in the City of Key West, just 90 miles from Cuba. The Florida Keys, known locally as "The Conch Republic", is a spectacular and laid-back sub-tropical paradise, surrounded by the turquoise waters of the Atlantic Ocean and Florida Bay/Gulf of Mexico. The Keys feature great fishing, kayaking, snorkeling and diving, hotels, resorts, B&B's and cuisine and cocktails to fit every budget. There is entertainment to fit every taste, important history and a unique culture, sunsets that will keep you spellbound, special events going on throughout the year including the KEYS100, of course, and you don't need a passport to visit here! So, what are you waiting for? We've saved a space for you!
