A young group of cheerleaders from Warren County learned last weekend that hard work, practice and self sacrifice can earn national championships. Warren Energy, a cheerleading squad comprised of 22 girls ranging from ages 5-11, won the Athletic Championship National Competition held in Chattanooga last Saturday.Warren Energy claimed its third straight victory in Chattanooga, but none of its wins were bigger than defeating three other squads at the Athletic Championship.Competing against three other talented squads, including last year’s national champion Stingrays from Marietta, Ga., Warren Energy claimed the championship with a dramatic come-from-behind victory on the final day of competition.Warren Energy found itself in second place after the first day of competition, trailing the Stingrays. To make matters worse, one of the team’s key members started to develop an illness that jeopardized her ability to compete.Kennedi Pegg, one of the youngest team members at age 7, became very ill and had to be taken by ambulance to Erlanger Hospital after Friday night’s performances.Pegg didn’t arrive back to the team hotel until 5 a.m. Saturday morning, where she rested until noon.
