Setting records and creating history has become second nature to Veronica Campbell-Brown, who would no doubt be an even bigger superstar in Jamaica had Usain Bolt not come along.
Bolt's triple gold medal-winning heroics at the Beijing 2008 Olympics overshadowed the achievements of fellow sprinter Campbell-Brown. The powerful runner, who is small in stature, claimed 200 metres gold in China to equal the record of East Germany's Barbel Eckert-Wockel of winning back-to-back Olympic titles in the event.
Setting new benchmarks has been something the Jamaican star has made a habit of during her athletics career.
In 1999, while still at high school, Campbell-Brown won the World Youth Games 100m title and a year later, she became the youngest Jamaican female to win an Olympic medal when claiming silver in the 4x100m relay at the age of 18.
More history followed in October 2000 when she became the first female to claim the 100m and 200m double at the World Junior Championships in Chile.
Then, at her second Olympics at Athens 2004, she won 200m and 4x100m relay gold, as well as 100m bronze, to become the most successful Caribbean athlete at a single Olympics - at least until Bolt arrived on the scene.
Her 200m victory, meanwhile, also made Campbell-Brown the first female from the Caribbean to win an Olympic sprint title.
But she was far from finished.
At the 2007 World Championships, she was the first athlete to complete the collection of youth, junior and senior world sprint titles with gold in the 100m final in Osaka, while her victory also made her the first Jamaican to win a senior global 100m title.
More gold followed at the 2010 World Indoor Championships in Doha over 60m - a title she has recently defended - and then a superb outdoor season culminated in her setting the leading times over both 100m and 200m and edging out American rival Allyson Felix to claim gold in the latter event at the World Championships in Daegu.
That sent Campbell-Brown into the Olympic year full of confidence and in superb form to achieve more success as she continues to demonstrate a level of sprinting excellence that keeps even Bolt on his toes.
