Cindy Sember

Cynthia Nonyelum Sember is an American-born British track and field athlete, specialising in sprint hurdles.

She finished fourth in the 100 metres hurdles final at the 2016 Olympic Games as a 22 year old but suffered significant injury set backs thereafter which interrupted most of the next Olympic cycle. Her first major international medal, a silver at the 2021 European Indoor Championships sparked a return to form and fitness that saw her finish fifth at the 2022 World Athletics Championships, and secure bronze for England at the 2022 Commonwealth Games, her first senior outdoor medal. She made the final of the same event at the 2022 European Athletics Championships but a stumble left her in 8th position in her third major final of the year. Her time in the World Championships semi-finals, 12.50, is a British record in the outdoor event. Her 12.38 from the final is the fastest time ever run by a British athlete in the event, but was wind-assisted.

Domestically, Sember is a five-time British champion in the 100 metres hurdles.
