British sprinter Chijindu Ujah, widely known as CJ Ujah, is one of the fastest runners Great Britain has produced in recent years. He gained fame for helping Britain win major relay medals and becoming one of the few British athletes to run the 100 meters in under 10 seconds. However, his career faced a major setback due to a doping case linked to the Tokyo Olympics. Since serving his suspension, Ujah has slowly returned to competition and is striving to rebuild his athletic career.
Early Life and Education of CJ Ujah
CJ Ujah was born on March 5, 1994, in Enfield, London, to Nigerian parents. He grew up in North London and attended St. Matthew’s CE Primary School and later Bishop Stopford’s School. After completing his secondary education, he studied at Sir George Monoux College in Walthamstow. He later earned a sports science degree from Middlesex University. From a young age, Ujah displayed exceptional speed on the track, quickly emerging as one of Britain’s top young sprinters. In 2013, he won gold in the 100 meters at the European Junior Championships, coached by Jonas Tawiah-Dodoo.
CJ Ujah’s Rise in Sprinting and Relay Success
Ujah became widely known in 2014 when he ran the 100 meters in 9.96 seconds in Hengelo, Netherlands, becoming the youngest British sprinter to break the 10-second barrier at that time. He went on to represent Great Britain’s men’s national athletics team at major international events, including the Olympics and World Championships. One of the biggest moments of his career came at the 2017 World Championships in London, where he ran the first leg for Britain’s 4x100m relay team, which surprised the United States to win gold. A few weeks later, he also won the Diamond League 100m title in Brussels. At the 2016 Rio Olympics, he narrowly missed reaching the 100m final by just 0.01 seconds.
Tokyo Olympics Doping Case and Medal Loss
At the delayed Tokyo Olympics in 2021, Ujah helped Britain finish second in the men’s 4x100m relay, earning a silver medal. However, shortly after the Games, his doping samples tested positive for the banned substances Ostarine and S-23. His “B” sample also returned positive. In February 2022, the Court of Arbitration for Sport officially disqualified Britain’s relay team, and the silver medals were revoked. In October 2022, the Athletics Integrity Unit imposed a 22-month ban on Ujah. The AIU and World Anti-Doping Agency determined that the violation was not intentional and was linked to contaminated supplements purchased online.
CJ Ujah’s Comeback and Recent Updates
After completing his suspension in 2023, Ujah returned to athletics. In 2024, he was recalled to Britain’s relay squad for the World Athletics Relays and also competed at the 2024 European Athletics Championships in Rome, where he openly discussed learning from his mistakes and working to rebuild his career. While some online reports mention a net worth of around $5 million, there is no officially confirmed figure for Ujah’s earnings or wealth.
Cryptocurrency Fraud Charges
Recently, CJ Ujah was charged in an alleged cryptocurrency fraud case. Prosecutors claim that the group targeted victims through fake calls, pretending to be police officers and crypto company staff. Authorities stated that one victim lost more than £300,000. Ujah appeared in court on April 30, 2026, and was granted bail. His next court hearing is scheduled for May 28 at Chelmsford Crown Court.
