  The Captain's Wave:

  The Captain's Wave is for those athletes that have their sea legs and are experienced triathletes wanting to race, and is designed to add additional safety and fairness within the races. If your athlete is on a racing team, has a coach, routinely places in other youth races, and wants to test their skills against the other experienced athletes, then the athlete may qualify to compete in the Captain's Wave. Your athlete should be familiar with all aspects of triathlon, including the rules and regulations for youth triathlons (drafting, spacing, passing, etc), and should have competed in a number of triathlons prior to this event. If you’re not sure which division is right for your athlete, send the Captain an email and we’ll help you figure it out.

  The Captain's Waves have separate awards from the age group division and only compete against each other. The athletes are numbered from oldest to youngest, and awards are based on the number of participants.
