More than 1,000 children from 6 to 16 compete in the decade old Big Swim day of free races in a 50-meter Olympic-sized pool at Manhattan's Asphalt Green. Kids are met at the finish line by Olympians and all participants take home a medal, photo, other goodies, plus all-important memories. Call (212) 369-8890 for more information.
