Mighty North Fork Triathlon

Mighty North Fork Triathlon benefits CAST.
While this is a great event for everyone, it is a particularly great race for first-time triathletes. It is a beautiful, most welcoming course with a calm bay swim, then a mostly flat, scenic bike course and an equally scenic run. Held in the heart of Long Island’s wine region, this event has something for athletes and spectators alike.

  • Swag for all participants (guaranteed if you are registered by 5/20)
  • Awards and amazing raffle prizes!
  • Beautiful course through the quaint roads of Southold
  • We bring the EVENT, you bring the POWER!
