Caren Guyett admits a tendency to sell herself short in conversation, but her sweet humility co-exists with fierce competitiveness. The latter trait, along with natural athletic ability and resolve, won her the title of American Ironwoman at this summer’s 44th annual Nautica United States Lifeguarding Association National Championships in Manhattan Beach, California.

“Every single year I think I’m going to lose,” said Guyett, a member of the Barnegat Light Beach Patrol who has competed at lifeguarding nationals the past three years, in addition to local and international contests.
