Henry competed only in the women's 50 m freestyle at the 2000 Summer Olympics in Sydney. She received a ticket from FINA, under a Universality program, in an entry time of 29.99. She challenged seven other swimmers in heat three, including Nigeria's top favorite Ngozi Monu and Aruba's 15-year-old teen Roshendra Vrolijk. She posted a lifetime best and a Saint Lucian record of 28.81 to scorch the field with a quick pace for the fourth seed. Henry failed to advance into the semifinals, as she placed sixtieth overall out of 74 swimmers in the prelims.
