Voting is open for the BBC Sports Personality's World Sport Star of the Year 2024 award.
Six contenders have been shortlisted for the award, which will be presented during the show live on BBC One on Tuesday, 17 December.
The 2023 World Sport Star award was won by Manchester City footballer Erling Haaland.
Who are the World Sport Star contenders?
Simone Biles
Sport: Gymnastics Country: United States
Three years after suffering the 'twisties', which led to her pulling out of several events at the Tokyo Olympics with the disorientating mental block, Biles was back to her brilliant best at this summer's Games in Paris.
Biles - the world's most decorated gymnast - won three gold medals, in the all-around, vault and team events, as well as floor silver.
The 27-year-old became the oldest gymnast to win the women's all-around title for 72 years in an event in which the previous 12 Olympic champions were all teenagers, and she now has 11 Olympic medals to add to the 30 she has won at World Championship level.
Caitlin Clark
Sport: Basketball Country: United States
Clark was selected as the number one pick in the 2024 WNBA draft by the Indiana Fever, and set regular-season records for assists (337), points by a rookie (769) and three-pointers by a rookie (122) in her debut campaign.
Earlier in the year, she became the all-time leading scorer in men's and women's college basketball with 3,951 points for the Iowa Hawkeyes, breaking the record held by Pete Maravich for 54 years, as well as making a NCAA record 201 three-pointers in her final season.
The 22-year-old's performances led to record viewing figures in the US, with 18.9 million people watching this season's NCAA final.
Catherine Debrunner
Sport: Para-athletics Country: Switzerland
Wheelchair racer Debrunner won an incredible five gold medals at the Paris Paralympics across a variety of distances from 400m to the marathon.
She also won silver in the 100m to take her Paralympic medal haul to eight from two Games.
Earlier in the year, 29-year-old Debrunner - also a five-time world champion - won the London Marathon for a second time, retained her Berlin Marathon title, then smashed her own course record in Chicago to seal a second successive Abbott World Marathon Majors series title.
Armand Duplantis
Sport: Athletics Country: Sweden
Duplantis, more commonly known as Mondo, is regarded as the greatest pole vaulter of all time and enjoyed another record-breaking year in 2024.
The 25-year-old retained his Olympic title in Paris, becoming the first back-to-back Olympic champion in men's pole vault since the 1950s, and in doing so, broke the Olympic record and the world record - the latter for the ninth time in his career, and second this year.
He went on to break the world record again later in August, setting a new best of 6.26m at the Diamond League meeting in Silesia, and also won a second world indoor title and third European gold in 2024.
Sifan Hassan
Sport: Athletics Country: Netherlands
Already a three-time Olympic medallist from Tokyo 2020, Hassan won another hat-trick of medals in Paris this summer.
After winning bronze in the 5,000m, the 31-year-old won the same colour over 10,000m before clinching the Olympic marathon gold on the final day of the Games - sprinting to beat Ethiopian world record holder Tigst Assefa by three seconds to set a new Olympic best of two hours 22 minutes 55 seconds.
In adding the marathon to her 5,000m and 10,000m titles from Tokyo, Hassan became the first woman to win Olympic gold in all three events, and the first athlete - male or female - since 1952 to win a medal in the three races at the same Games.
Leon Marchand
Sport: Swimming Country: France
Marchand cemented his place as a global swimming superstar in 2024 by winning four golds at his home Olympics in Paris.
The 22-year-old - a five-time world champion - won the 400m individual medley before his remarkable feat of securing gold in both the 200m butterfly and 200m breaststroke inside two hours, both in new Olympic record times.
Marchand, widely compared to American great Michael Phelps, won his fourth gold in the 200m individual medley to become the first French athlete to secure four gold medals at the same Olympic Games, and also helped his country to bronze in the 4x100m medley relay.
