  The Pigman Sprint Triathlon is a favorite for top pros, serious amateurs, recreational racers, and first-time triathletes. This .5K swim, 25K bike and 5K run sells out very quickly because it's the perfect way to start your summer triathlon racing season. The Pigman Olympic Distance (1.5k swim, 40k bike, and 10k run) ups the challenge.

  Relay Teams

  Relay teams are welcome at the Pigman. Top Male, Female or Coed teams will win awards.

  Time-Trial Swim Start Format

  Elite athletes and teams will start in waves beginning at 7:30am. All other athletes will start in a Time-Trial format. For the Time-Trial start, athletes will line up according to their respective age group wave (Triathlon age is based on your age as of 12/31 of race year). One person will start every 3 seconds by crossing over the chip timing mat on the beach before entering the water.

  Timing Method

  The Pigman Triathlon will be chip timed
