The Swim portion of the triathlon will be a 375-yard serpentine-style swim in the Chinle Aquatic Center pool. (This is equal to 15 lengths of the 25 yard pool.) Swimmers will start based on their estimated swim time, in 30-second intervals, and swim "serpentine-style" up and down each lane, completing the swim on the opposite side of the pool, where they will get out of the water and head to the transition area.
