The children's race was one of 10 races in the 2012 Commanding Officer's Fitness Series. Starting at Hangar 101, the first group of children, ages 7-10, began with a 100-meter swim, followed by a 3-mile bike ride and finished with a 0.8-mile run. The second group of children, ages 11-14, completed a 200-meter swim, 6-mile bike ride and 1.2-mile run. The race was a pre-cursor to the adults' Tradewind Triathlon held the following day.
