Her coach, Koketso Mogapi, has been instrumental in her success. Semenya's dedication to the sport is evident from her early achievements. She was South Africa's flag bearer at the opening ceremony of the 2012 Olympic Games in London.
Semenya faced significant challenges throughout her career. A knee injury after the 2012 Olympic Games kept her out for almost a year. She also missed the 2010 Commonwealth Games in Delhi due to a lower back injury.
Despite these setbacks, she returned to competition in July 2013. Her resilience and determination have been key factors in her continued success.
The International Association of Athletics Federations (IAAF) introduced regulations in November 2018 requiring female athletes with differences of sexual development (DSD) to take testosterone-reducing drugs. Semenya appealed against this rule but was unsuccessful.
The Federal Supreme Court of Switzerland temporarily suspended the ruling but confirmed it in September 2020. As a result, Semenya could not defend her 800m gold medals at the Tokyo 2020 Games.
Semenya initially planned to switch her focus to the 200m event for Tokyo but later decided against it. In April 2021, after winning the South African 5000m national title, she said, "I'm getting old‚ I'm scared to tear my muscles."
She emphasised that distance running made more sense for her at this stage of her career. "We're happy with what we're doing‚ we're having fun," she added.
Semenya is married to Violet Raseboya, who has also competed in distance running at a national level in South Africa. They have one daughter born in 2020.
In addition to her athletic career, Semenya pursued higher education. She completed a diploma in sports science at North-West University and studied at the University of Pretoria.
Semenya's sporting philosophy is simple yet powerful: "It is not about what people think of you; it is about proving them wrong." Her hero is Mozambican middle-distance runner Maria Mutola.
Known by the nickname "Cobra," Semenya's journey has inspired many young athletes worldwide. Her story is one of perseverance and dedication.
Looking ahead, Semenya aims to continue competing at high levels despite the challenges posed by new regulations. Her focus on distance running reflects her adaptability and commitment to the sport she loves.
Semenya's impact on athletics extends beyond her medals and records. Her fight against regulatory changes highlights broader issues within sports governance. As she continues her career, she remains a significant figure in athletics.
