Spectator parking and the shuttle are free; spectators must stay out of the transition area and may use a trail from the spectator area to the beach. Folding chairs are allowed for spectators.
The kids triathlon is for ages 5 to 12. Children use the outside of the swim buoys, may stop and hold on, and may wear life vests. Parents may follow inside the buoys. The kids' bike course uses the first half of the adult run trail for ages 8 and under and the full adult run trail for ages 9-12. Kids finish on the same line as adults.
