The modern pentathlon will undergo significant changes after the Paris Olympics, eliminating horse riding in favor of obstacle courses inspired by 'American Ninja Warrior' for the 2028 Los Angeles Games. This decision comes after years of controversy, including a notable incident where a coach struck a horse during the Tokyo Games. Athletes like Britain's Joe Choong, a gold medalist from Tokyo, express mixed feelings about the transition, fearing it may alienate top competitors in an already niche sport. The sport, which has included horse riding since its Olympic debut in 1912, was designed to test skills relevant to a cavalry officer's duties. As the competition approaches, Choong also grapples with the emotional challenge of competing without his girlfriend, who failed to qualify for the Games. The changes have sparked debates on whether this modernization is necessary for the sport's survival or a misstep that may diminish its historical essence.
