After checking in, please go to the body marking area. Your race number will be marked on the leg and the arm. These markings are used to identify you at the start and end of the swim, as well as during the bike portion of your race. Race Day Events provides its participants with latex swim caps. The color of these swim caps denotes which wave you will be participating in. If you have a latex allergy, we encourage you to bring your own swim cap. The non-latex swim cap does not need to be the same color as your wave color, but if it is, that would be appreciated. If you do not have the same color, please alert the race official of your latex allergy before your wave enters the water.
