Courtney and Kelley Hurley have competed at a combined three Olympic Games, but they have never competed against each other at the Olympics. That will change this August at the Rio 2016 Olympic Games.

The sisters have both qualified for the women’s epee fencing individual and team events in Rio, marking the first time they will compete both with and against each other in Olympic competition. Courtney and Kelley are ranked first and second in the national senior team point standings and, despite two events remaining before the end of the standings, the Hurleys are mathematically guaranteed to finish in the top two spots and punch their tickets to Rio.

Kelley, 27, finished 20th at the Beijing 2008 Games, where only an individual competition was held for women’s epee. Four years later, Courtney, now 25, qualified for the 2012 Games while Kelley just missed the three-member team and went to London as the replacement athlete for the team competition.

Courtney finished 22nd individually in London and Kelley was granted the opportunity to compete in the team event. The Hurleys, along with Maya Lawrence and Susannah Scanlan, won the bronze medal, the only medal earned by the U.S. fencing team in London and the first U.S. medal won in the event.

In Rio, the Hurleys will be joined in both the individual and team events by one other U.S. fencer, who is guaranteed to make her Olympic debut. The national standings come to a close April 11 and the two women battling it out for the final spot are No. 3 Katharine Holmes, a 2010 Youth Olympian and 2015 Pan American Games champion, and No. 4 Katarzyna Trzopek, a member of the Pan Am Games gold-medal-winning team. The fourth-ranked athlete will be named the replacement athlete for the team event only.

Courney and Kelley Hurley join women’s saber fencers Mariel Zagunis and Ibtihaj Muhammad, and men’s foil fencers Gerek Meinhardt and Alex Massialas on the 2016 U.S. Olympic Team.

The Hurleys were one of nine sets of U.S. siblings to compete at the London 2012 Olympic Games and are the first siblings to qualify for the 2016 team.
