CELEBRATING 45 YEARS.......
Long considered one of the east end season openers, the RJA Memorial is one of the longest, continuous triathlons on Long Island! We will be celebrating our 45th anniversary this year.

The recently added Sprint triathlon consists of a 1/2-mile swim, 14-mile bike and 3.8-mile run. The Olympic race/Aquabike goes off at 7:30am and the Sprint follows at approximately 8 am.
